Two significant adds to c.1983 Heuer card page...

Good Morning [Afternoon, Evening...] This morning I received four scans from Greg Wade of c.1983 Heuer data cards to add to the page I have already posted on-line. Each card is notable and significant... The first card provides us with the first printed information on the exceedingly uncommon and rarely seen Gold 510.508 Lemania 5100 chronograph: Not many Lemania 5100's were ever put in a gold case! The second card provides us with perhaps the best explanation of the rationale behind Regatta watches: It all seems much clearer and easier to understand now! Thanks are due to Greg for his contribution to the knowledgebase existent on the Internet. Cheers! -- Chuck
