for an airsoft conversion, there are 2 that you could use , one for the grip and back part, and the rest for the double barrels, but there's still a bit of greebles to sort out. I think makign it ouw od wood, PVC, ect would be the best way to go if you want to get an accurate looking one. However this is based on the judgement of only seeing ONE side of it, so if someone could please scan all the reference available in the comics, that would be great! Just pm me so I can give you my e-mail address. I dont need far shots, just the best refernce pics that you think I could use. Again, thanks a bunch!
