I have a Sensenich prop with a stamping of

I would appreciate any help. I can only find a rough estimate of 1932-1943. Thanks dale

If you're sure both digits are "6" then my best guess is that it was for a Mooney based on a 66 inch prop shown on this page. I'm not sure what the "CB" suffix is in that list, but it's the only plane shown using a 66 inch prop.

To my knowledge there is no accurate listing of dates of manufacture prior to the "B" prefix on the serial number.
