The models are old (very old!) Wargames Foundry metal models and could not find in the websote (probably out of production by now). These are true 25 mm scale and when compared to some of the current ranges in the market (particularly Victrix and Warlord), they look like dwarves!! (in the photo below one of the WF side by side with a Victrix Roman Auxilia model).
Even though these archers may be a bit diminutive by modern standards they still look the business, Benito. I really like the natural earth tone palette you've used for them, it seems spot-on for the period. This all being said, I think you should keep one of your original 'orange fellas' to be the veteran leader of the unit. He can wax poetic to the young recruits about how vibrant and citrus things were in the Old Days. :)
30 point for you Benito. Well done and Merry Christmas!
