My 1976 dated Roy Baker's Pancake Holsters catalog gives only model numbers-175,275 etc. up to 775 and the standard model 271. No size codes listed.
The introduction refers to Roy's teacher- " perhaps the greatest leather artisan in America's history." What do you bet Red knows who that is ?

For the OP: there were several 'eras' of the Baker pancake, and so I expect that markings varied between/amongst them. One tells them apart by the Baker maker's mark. Roy sold up circa 1980 on a high, died 1990 (Jim Buffaloe said that Roy drank and womanised himself to death).
'Perhaps the greatest leather artisan in America's history'. Don't know who that was. To guess -- I love to try to figure things out -- would require us to work out if this was literally true (someone like F.O. Baird who worked for Myres) or hyperbole meant to make Roy look good (like the posts we see on forums when someone receives the finest holster they've ever seen).
I couldn't work out any reasonable view that Roy studied with Floyd Baird (who indeed was a leather engraving teacher/master) eventually I decided his statement was not to be taken literally (such as 'artisan').
Roy was an Arkansas boy born around 1920, married WWII (likely he served) and lived at that time in Fort Smith, AR. He shifted from AR late '50s and ended up in the holster business. Died, as said, around 1990.
Know who else did all those things, at exactly the same time in exactly the same place? Andy Anderson. Though there's nothing about the pancake, an admittedly brilliant invention, that suggests an Anderson influence. Andy was a trained artist and was at his peak around 1970; that ended in 1971 when both the Sylmar quake destroyed Andy's shop and the Baker patent was filed (coincidence). Strokes then put an end to Andy's career in '74. A silent homage to Andy would have been relevant at just that period.
Plausible.
