The site below, under "DATING CONTEMPORARY FENDER AMPLIFIERS", tells how to read the code. The sticker looks like this, and should be inside the cab somewhere.

I just bought a USA Made, silver faced Fender Hot Rod Deville 410. I have searched and searched and cannot find the manufactured date or just the year at least. Hi Love Your Monster Music, I believe that US made means 2001 or before.
There may be an inspection sticker with a two letter code indicating the date of manufacture.
These are marked with EIA code “606” which is the company number for Schumacher.
Well, this universal “truth” was debunked when we found a bunch of amps with transformers made by the Better Coil and Transformers company.
Some things are very obvious such as non-original or reconed speakers, non-original transformers, replaced pots, re-tweed, re-tolex, re-grill, etc.
and these changes are often disclosed and of a non-malicious nature.
A 1957 tweed Vibrolux was reported with a tube chart printed with circuit “5E3” (tweed Deluxe) instead of the correct 5F11 (see photo).
Clearly Fender wasn’t afraid to use incorrect parts when they were in a bind. The 5G12 Concert is the earliest version from very late 1959 and early 1960 so the existence of a tweed example, while extremely rare, is certainly plausible since Fender was making lots of tweed amps during the same time period.
Greg and Devin's experience meshed well with mine since I'm essentially the blackface/silverface amp guy (amps made between 19) in the group.
