First visit to Mercedes-Benz Stadium with the Viceroy (Autavia ref.1163v) to see Atlanta United FC vs. the LA Galaxy:
The first serial number for a 950 appears to be 2457001. The 950 was introduced in 1910, so yours is a fairly early one. Your serial number is 2457768. That means it might well have been completed in 1910 or 1911. 115 years old and it is pristine. You really know how to pick 'em!
Wha... Thought I'd seen most of the Speedy variations but can't recall that case. What model is that? ... Good looking beast though.
That is a stunning piece. What's its vintage? Is the crown recessed or some other mechanism for setting/winding?
Now that is cool! I was at school when these came out and remember the school banning them as kids were trying to cheat their maths tests (not allowed to use calculators back in the dark ages...)
