german large frame revolver

[toomanymachines]

I need the bolt from a german large frame revolver. or at least the little part that locks the cylinder from turning.
I see marstar has everything for that type of gun as sold out. Does anyone know of a source for what I am looking for. Preferably in Canada. gun part unlimited has that part as sold out as well.
thanks in advance.
