New member here. I found this in my grandfather's old chest with a bunch of other things from the early years. My assumption is that it is from the 1960's or so. 1. What model is this? 2. How much is it worth? I don't plan on selling it - but would like to know for the heck of it 3. Estimate repair cost? The dial is messed up and it doesn't seem to charge by turning the crown or moving it around Thanks!
