Aermotor date stamp

[Smax]

Has any body ever saw a date stamp on a aermotor x702 with only the letter k7 just as I typed it no other marks on the hoop

I have never been a big believer in this, I have several heads with weird stuff that sure isn't a date. I think I got one with a J9 or something like that, maybe its a K also?

This one is clearly a k thought it might have been a factory rebuild or something like that

On my 16ft there doesn't appear to have ever been a stamp at all, I polished it all over looking.

I have a 10 ft 602 that does not have any markings as well.

On the early 602's generally before 1919 the year is stamped on the end of the main shaft. You might find a date there...

Interesting. I just went out and took a look at mine. Stamped into the end of the shaft is the following:

IUMM
C Is this a date code? If so,is it decipherable?

Thanks,

Attached is pictured a hub that I saved from an old wrecked A602 that shows the date stamp fairly well. 18 is stamped twice.

I looked at my 602. On the flat spot on the hoop at the top is a Z then a 7 then a 22. So I was thinking July of 22. ??
