Hi,does anyone know what the case number would be on a 1967 Aerojet?
Looking at the examples we have on site I cannot see any case model stamp in the usual place, but the following may hold some clue as to what they were.

It would depend on the type of movement (manual or self winding) and either stainless or gold plated. There are likely several different cases, but some that I have had are:
2703 - SS Manual-wind
2705 - SS Self-wind
388 - SS Manual-wind
Others on this site:
2702 - Yellow Self-wind
456-1 - Yellow Self-wind
2704 - SS Self-wind

Ahhh that's what I get for not checking all the examples on site.
Nice work Ken.
Thanks for the info Ken but I just realized all I have is the ABC case supplement which doesn't have these numbers so I just found one on e-bay and its on the way
