Nice Bruce! She's going to turn out well I'm sure!
I am not aware of *any* Chinese type 56's arriving from China with phenolic 'jungle' stocks. Of course, because I'm not aware of it doesn't mean it didn't happen.
I am aware of some of the SinoBanian imports from Albania coming in with beat up phenolic stocks in place, covered in grease & grime, obviously restocked prior to import. No idea if this was official arsenal work or done by Spiro down in the basement because he carved his original wood stock to the point of un-usability.
