Anyone have a idea about what year this M/T center cap is?

I found a set of these while digging in my dad's garage, anyone have any idea what year these might be, I am thinking late 60's.

 

i think they were being sold in the mid 70's still... havent seen any in quite a long time.....

 

Those were sold to go on the M/T wheels that had steel chromed hoops and an aluminum center section if my memory serves me correctly. I could be wrong though.

 

They are super cool> I think they may have been for the RADIR style wheels?

 

cant answer your question but that is a super cool center cap

i have 3 m/t center caps that are a different style from yours mine look plain compared to yours id like to find a 4th to go with mine

 

Yes, M/T Rader series. There were 2 styles of the spinners. Starting in 65 I think, when Mickey got involved with the former Rader Wheel Co?

 

Thanks everyone.
