Type 2 Paratrooper help.

[Pphilly]

Hey everyone, I have a T2 rifle but it is missing the forestock collar, #48 in the diagram. Does anybody have a line on something like this? I have already contacted Don, from Don's reproductions and he does not make this part. Any help is appreciated, Thanks!

However, Gunparts lists Type 99 parts. No Para models though.
