What does a “u” in my serial number mean?

I get that the H means 1991 and the 093 is the 93rd day of the year but what is the U1? Sorry if this has been addressed, I tried to read a bunch before posting. Thanks!

Maybe its an incomplete "0" It looks too short compared to the other letters and numbers. I might just be seeing things though.

Hmm, I'll bet you're right, it does look shorter.  Thanks, that's really been bugging me, I've been looking everywhere for what a "U" could be!

Unicorn.  I'll bet it's the only Heritage guitar in existence with that serial number.

Its a zero

Zero

Got that sorted out.  The numbering machine for serial numbers was always suspect.  Most likely the reason newer models are hand printed serial numbers.

But the guitar is a TEN!  sweet!

[davesultra]

Yup, it’s an incomplete “0”.

[golferwave]

01 means it was the first guitar completed on that day.

Also, it wasn’t made on the 93rd day of the year. For heritage guitars, you take 365 and subtract 93 days from the end of the year. Yours was made on the 272nd day of the year.
