G'day Andy,
There pretty thin on the ground, as you would already know, but I've seen a few 50's frames for sale in the last
couple of years. I was chasing a '63 frame, almost impossible to find in Aust., but they pop up in the States,
after a couple of years looking I found one in the US, was cheap but freight wasn't. If you are going to import,
make sure you do your homework on importing. Keep looking on Ebay & put a wanted add in just bikes,
even though I got some pretty strange callers on that one!, had a guy that kept sending me text messages
that he had a frame, but wouldn't answer his phone....some kind of scam I suspect, & a few guys that had
frames for different years, & a couple of guys that had no frame at all, but just wanted to talk about bikes!
Good luck, I keep my eyes peeled as well,
regards, Cus
