I don't know much about the Sinn lineup, especially any earlier models. Just came across this one which drew my attention for being a nice "type XX" derivative. Indicated as an earlier model with a 7750 in it?
I can't find the correct model and... how come the lumed indices look so horrible and there's sloppy execution of the subdials? Weirdly generic unsigned caseback?
The Vintage Sinn Collector has a similar model listed as Sinn 103 B SA HD, however the bezel is different and clearly the indices don't flow out onto the subdial
I'm not sure what to make of this. Do people make Sinn fakes or frankens?!
