Parts needed for 37S Double-Dial Waltham

[sderek]

I need a winding pinion for my double dial waltham serial number 27912210. Does anyone know the part number? The inside diameter (diameter of stem) is .101 inches.

I have 2 other 37S Waltham's (serial numbers 18144216 and 22795945), with what appear to be identical movements, but the inside diameter of the winding pinion is .1018 inches.

I've tried swapping out the entire stem, but the pinion outer diameter is too large to be used in the double dial Waltham.

Apparently I need a winding pinion for a 37S Model 1926 Waltham.

The other 2 Walthams I have are Model 1910's.

Anyone know the part number, and where I could find one?

Thank you!

My Waltham parts catalog of 1948 did show a different winding pinion for the 1926 with 13 teeth, part number 28085, the Model 1910 used a 28084 with 15 teeth, hope this helps.
