Dial feet positions: 1950s bumper vs full rotor Constellations

Good evening,
I’ve recently received a few dials for 50s Connies and was wondering if one of you knowledgeable gents knows the dial feet positions of bumper Connies (cal 352/354; ref 2652, 2782) vs full rotor Connies (cal 501/505; ref 2887, 2852) off the top of your heads. If I remember correctly, they’re not interchangeable so I figured the feet positions would be an easy way to distinguish between the movements.

The dials I have have feet at 11 and 5.

Thanks a lot!

Cheers
Matt

Hello 😀

I figured that using the original omega technical sheets would be good to show where the dial feet are.
I pointed them with red arrows.
You can use the crown stem as a reference for the positioning.
