I was referring to the helmet of the figure with the long shield but this is not bad either.

*Some important observations: I don't know which headless statues he refers to in the description, but I have never read anything about the Lusitanians wearing metal cuirasses, the same goes for the greaves in figure 114. If we remove those details, perhaps these images can be of some use to us. In the case of the leather helmet in figure 113, it is taken from the reliefs of Osuna, which are from the Iberian zone, but since we don't know what these helmets looked like, we cannot say that this is an error.

I have only seen that representation in a very unreliable drawing, I think it is not worth.

Like here

Maybe you should recolorized the helmet to more iron tone or directly change it for a non cheek-padded montefortino.

The one with the long shield yes but the tricrested no.

"6 At any rate, the Lusitanians, it is said, are given to laying ambush, given to spying out, are quick, nimble, and good at deploying troops. They have a small shield two feet in diameter, concave p73 in front, and suspended from the shoulder by means of thongs (for it has neither arm-rings nor handles). Besides these shields they have a dirk or a butcher's-knife. Most of them wear linen cuirasses; a few wear chain-wrought cuirasses and helmets with three crests, but the rest wear helmets made of sinews. The foot-soldiers wear greaves also, and each soldier has several javelins; and some also make use of spears, and the spears have bronze heads. Now some of the peoples that dwell next to the Durius River live, it is said, after the manner of the Laconians — using anointing-rooms twice a day and taking baths in vapours that rise from heated stones, bathing in cold water, and eating only one meal a day;76 and that in a cleanly77 and simple way. The Lusitanians are given to offering sacrifices, and they inspect the vitals, without cutting them out. Besides, they also inspect the veins on the side of the victim; and they divine by the tokens of touch, too. They prophesy through means of the vitals of human beings also, prisoners of war, whom they first cover with coarse cloaks, and then, when the victim has been struck beneath the vitals by the diviner, they draw their first auguries from the fall of the victim. And they cut off the right hands of their captives and set them up as an offering to the gods." Strabo. Geography III. Chapter 3: https://penelope.uchicago.edu/Thayer/e/roman/texts/strabo/3c*.html

I am going to continue posting the information I find about Lusitanians here, but as far as I know, there is very little and in general the experts base their investigations on what was found in the Galician area, although the degree of relationship between Galicians and Lusitanians is not entirely clear.

In article of 2011 Quesada said about Lusitanian weaponry: "Most of Viriato's men would cover themselves with the heavy woolen cloak or sagum and carry weapons such as a spear or a circular shield, in addition to perhaps a short antennae sword or a dagger. The typical falcata of the southeast of the peninsula was a rarity in the Lusitanian area." Reconstruction of a Lusitanian warrior of the 2nd century B.C. by Marek Szyszko.(*his shield boss was proper of the vettonic area during the 2nd century BC) Vettonic knight of the 3rd century BC reconstructed by Carlos Fernández del Castillo. (*The Lusitanian weaponry is not well known but it is believed that it would be very similar to that used by their neighbors the Vettones.)

Archaeologically there is hardly any information about the Lusitanians, so it is difficult to reconstruct their panoply. I have seen the tricrested helmets reconstructed in many ways, like this (in some very unreliable works of art), like Montefortinoes... I have sometimes thought that if Diodorus Siculus said that the Lusitanians used the same weaponry as the Celtiberians and the Hispanic-Chalcidic helmets have been very widespread in the Celtic area, perhaps with "three-crested helmets" he refers to it, but it is only a theory and I do not have any type of evidence to support it.

The one of the left without cheek pieces.

Something more like this:

We don’t have models of coolus helmet? It’s basically the same

Add to It a more round shape, without pointy corners like in this example:

We have evidence from the representations that the tribes of Spain and Portugal removed the cheek pieces from their helmets. This does not seem to have happened in the older models, the imported Gallic iron helmets, but yes in the helmets adopted after the Punic Wars. Warrior of Sanfins. Portugal. (*sculpture made by Gallaecians. we haven’t got much archeological data about the Lusitanians, so we will have to settle studying their neighbors) Viriato imagined by Carlos Fernández del Castillo with stolen Roman equipment,everything except the sword, that is from a peninsular model.

Another of the Osuna reliefs. *One of the warriors wears greaves because he is probably Roman. (2nd to 1st centuries B.C.) Reconstruction by Ángel García Pinto below the title "Spanish Caetratus 1st century B.C." The artist doesn't understand the warrior's clothes like a padded armor more like a striped tunic. Also the Roman sources don't mention anything similar to a padded armor so we can only speculate about the representations.

Celtiberian warrior of the 3rd or 2nd centuries BC by José Luis García Morán.

"And this people, it would appear, provide for warfare not only excellent cavalry but also foot-soldiers who excel in prowess and endurance. They wear rough black cloaks, the wool of which resembles the hair of goats. As for their arms, certain of the Celtiberians, carry light shields like those of the Gauls, and certain carry circular wicker shields as large as an aspis [Greek shield], and about their shins and calves they wind greaves made of hair and on their heads they wear bronze helmets adorned with red crests(*Purple in other translations). The swords they wear are two-edged and wrought of excellent iron, and they also have dirks a span in length which they use in fighting at close quarters. And a peculiar practice is followed by them in the fashioning of their weapons; for they bury plates of iron in the ground and leave them there until in the course of time the rust has eaten out what is weak in the iron and what is left is only the most unyielding, and of this they then fashion excellent swords and such other objects as pertain to war. The weapon which has been fashioned in the manner described cuts through anything which gets in its way, for no shield or helmet or bone can withstand a blow from it, because of the exceptional quality of the iron. Able as they are to fight in two styles, they first carry on the contest on horseback, and when they have defeated the cavalry they dismount, and assuming the rôle of foot-soldiers they put up marvellous battles." Diodorus Siculus 5,33(1st century BC)

I forgot to comment this. Yes, they would be accurate. Diodorus Siculus said that the Celtiberians wrapped strips of goatskin around their feet. It is possible that the Iberians had the same tradition but it is not reflected in their representations.

Southern Iberian noble warrior of the 4th century BC by José Luis García Morán.

They are reconstructions of Numancia, in the Celtiberian area. (*Metal greaves are an interpretation error)

Could you reuse the slinger design? It looks like one of the Despeñaperros figures (4th century BC) so it's pretty accurate

Some problems: The Hispanic-Chalcidic helmets (the one with the crest with feathers) are more common in the Celtiberian area, although there is at least one case in the Iberian area, in addition, the metal greaves are very very old (6th and 5th centuries BC).
