I have a junker PM OP that's on the 'to-get-rid-of' list. IIRC the chrome was still good. It's in Australia though, so I won't be able to get at it for another few months. I head back for late July/early-to-mid August every year.
I'm nominally based in Tassie, but this year I'm planning a WA trip to see friends and family, so if you're in Perth I could probably just hand it over to you directly come August. If not then you're still welcome to it, just cover the postage cost is all.
If you happen to have any spare parts for a
Stalker figure and/or any of the Predator missiles that'd make for a good trade IMO. Alternately, if you happen across any
Peanuts books at second-hand shops (Salvos etc.) my students would love that for some reading material. Japanese kids go nuts for Snoopy.
