Hi mate, I have these plans in Australia - looks like they're the last set in existence. They're getting pretty scrappy now and I need to digitize them anyway so they're not lost forever. There's a bit of scribble on them (not much) and they are yellowed and torn, so I will get them copied by a pro.
I was given them back in the early 80's and 3/4 built the model before leaving home and selling it. I've only just completed the second build and just about ready to fly.
If I can get a digital file from the printers I will try to upload them somewhere, otherwise would have to send you a live copy, which will cost.
Cheers.
