I have an early 18s, Model 1, serial number 27,000ish that I'm wondering if the click and click spring are correct. The click has a flat on it that I think should be for the spring, but the click spring goes way beyond it, and looks home made. Look at my picture and let me know what you think. If you have one of these movements, or a picture of one, I'd be grateful if you could post or e-mail me about it. Thanks.
