2 of 2 pre 1924 movements I picked up recently

I got this movement in a lot of movements I grabbed for spare parts.  This movement is 15 jewels but has no movement designation nor does it have a serial number.  What I found most interesting is that it is marked Tissot at the botton of the movement.  Bulova was getting very high end ebausch movements when they acquired this one.

 I like these old movts. Hard to say, but it is also possible that there are two movts represented here. The barrel bridge looks like it has lost less of its plating than the train bridges. That notwithstanding, Tissot also used ebauches from Swiss makers like AS and FHF. To know for sure, the movt can be identified by its keyless works, under the dial. There may even be a maker's mark under the dial, it was common for movts of this time period. The regulator is hard over to one side, and the hairspring might be damaged, but sometimes these old movts will respond well to repair attempts.

I'd read somewhere recently where Bulova stamped Movements had been seen in early Tissot or perhaps it was Tissot in Bulova. I need to find that article, NAWCC archives I think.
