Mine is either a 1966 or 1967 Celebrity III, to the best of my knowledge. There are a couple of things that I've noted as I've been looking at others. One, is that my strap pin is located directly under the neck joint instead of the upper left bout horn. I have not been able to determine why that is. I've seen older as well as newer Celebrity's with the pin on the horn. Was it an arbitrary placement at the factory? Also, I've seen discrepancies with the Mosrite label on the inside of the F hole. Mine says "Celebrity", I've also seen "Archtop", and "Celebrity #3".
So, here is mine, serial number N0772

the back

The body

So, come all you Celebrity onwers, let's see yours!
thanks
