I used to own a 'Tech 300. Was under the impression the full range carried a holographic sticker / decal, denoting tubing and individual frame number. I don't remember a BB code. In the example below, I'm sure the 'AA...' prefix signified 1991, year one of production. Wish I still had it!!
It might be that the lug numbers 3 and 4 denote angles - ie 73 and 74 degrees.

Edit: Retrobiker 'Bikemeister [?2000]' I think used to produce Dyna Techs. Apologies, bit vague ...
