Well I think I got pretty lucky anyways
Today I won a bid for a lot of ETA movements which includes:
3-4 17J movments 2846
1 21J movment
1 2824 movement
1 2834 frame
16+ 2836 movements in gold and a couple in silver with etching and blued screws
Considering what I won it for ($170.00 USD), I think I did pretty good. Of course not all of the movements will work, but I am pretty confident that I will be able to service/repair most of them
Of course, there is always the possibility that I got scammed, but I feel pretty good about this one.
