Thanks, George for this insight. Given that, and the reasonably good fit to the relatively small A-200 cabinet, this does seem a likely origin of this particular crank. Do you think you could shed a light on the question I've posted a couple of times over the past few days, regarding whether the user- adjustable (semi-automatic) stop on my ser. no. 1429 A-250 was the first type of stop scheme that Edison employed on the new Disc Phonograph? In this arrangement, there's a small round knob on the start lever, which can also serve as a manual stop lever. Any idea of when that type of stop was discontinued in favor of the more familiar type with the rigid stop trip lever on the lift post? I'd like to informally survey any owners of these early Edison Disc Phonographs that have this unusual early style stop, to find out the model and serial numbers of the machines that have it. To show graphically what I'm referring to, I can email a photo of this odd lever arrangement to anyone who might like to help. I'm hoping to use this detail and possibly others to learn approximately when my early A-250 was built.
