Roman crossbow

[Thomas V.]

So like the Grozer Roman Bow? I don't know how long it is but I think it's 130 or 150cm, and is symmetrical.

According to the homepage, it is 53 inches long when strung.

What kind of draw length are we talking then? 90cm?

Skimming composite bow reconstructions of different kinds, the draw length seems to range from c. 65 cm to c. 80 cm (26 to 32 inches). Considering the length of the human arm (c. 70 cm, according to Baatz) and the modern "standard draw length" of 28 inches, said range doesn't seem a stretch.
