Yes Patrik83, this seems like a possibility to me. I think X350 XJR was suggesting this too. However, the fact that most examples I find are of the "naked omega" variety, suggests to me that it is likely that this is a valid original bridge.
Also, I have never seen a movement that is labeled twice with the caliber number. So maybe there are two valid varieties. I should note that I am also very much a non-expert!
