Thanks! I took a gamble for this one, no movement pics, as seller states he doesn't want to scratch the caseback. 100% feedback was enough for me to pull the trigger for that dial and at a very reasonable price too. Looking most likely to be 2576 though. PS. It has Cal 344 so it is 99% 2576, you have an identical one in your collection right?
Though it will be hard to put it on anything. It's never even been fully out of its box; the end with the price tag is still connected to the bottom of the box with a wire through the end piece. Seller's photo:
Baby Ploprof on it's way to me from the Bay I actually needed to not spend any money this month due to a forced trip back to the UK. Oh well.
