Ok, I need the WRT detectives out there and their help. I've searched and as far as I can tell this symbol or trademark belongs to the Chicago Watch Co. 1895-1903 and made by Elgin. The movement came in an old but intact tin stamped "Elgin Watch Co. I looked up the serial # on PWD.com under 'Chicago' and that's what came up. But, there are a few pics of others and mine looks nothing like any of them nor has this trademark. Anyone recognize this trademark? It's a size 18s with no case. Aaaand I just noticed I didn't provide the serial number. I'll post it here in a bit. Thanks Mike
