Thanks, I've been around Ebay since 1998 so I understand it's a lawless place. I was thinking about assembling parts to make a 1675 or similar era Rolex. Having said that I am more leaning towards buying a project that is already done, and was just idly scanning Ebay thinking about prices and purchases.
A was toying with buying a really nice 1665 that was offered on the forum at around €2800 but I wasn't sure about taking the risk of buying from someone I didn't know.
Anyway, back to the research and the learning. Thanks all,
Charlie
