Hi, I've been reading this forum for a while now and decided it was time to register after having lucked out and purchased a mint model 18-3 s/n 6k73xx for US$475.00 (A$650) today.
I also have a 17-3 from the mid seventies so is the 18-3 a similar age?
I will post some pics when I get it in a couple of weeks ( its from another state - our annoying transfer laws in Australia)

Thanks
Darren
