I have a single trigger 28 repro with very nice wood(feather crotch), I also have a double trigger repro with OK wood(straight ribbon). It seems that I have heard they cannot easily be switched. Is that so?
Both splinter, both 28 ga.
I have never attempted to take any of my Repro's apart because I don't want to mess screws up.

Advice please?
