What we have here is a full metal PPK. I had a dude who collects lots of these give me his opinion as he was suspicious of it being a guarder metal kit. Turns out best guess is it may be a hodge podge between a Maruzen and an XDY which was a brand that made metal PPKs which were externally fun but internally bad. But we believe internals are Maruzen as it also accepts Maruzen mags, which the XDY should not normally. So long story short, I dont know EXACTLY what is in it but I know it is a functioning all metal PPK which holds gas and fires. And since I cant for sure say what it is I'm relisting it now at $100 shipped.
