Help identifying 60's B&W Motorola

Hi! I need a little help identifying this TV! (In order to hopefully get the SAMS for it, as the first step in reforming and possibly recaping, and ultimately restoring it.) As you can see from the pics it's a Motorola branded set. Model number might be G15A13, or that might be an unrelated stamp and the original model number sticker on the back lost. The chassis model number is VKTS-588YB-01.

Following the advice in other threads on the subject of schematics, I attempted to cross reference this on the SAMS website (and Google) but the only possibly relevant hit I was able to come up with was QUASAR VKTS588YA06 (thru B01) – SAMS #719-3. However, I’m pretty sure this set predates Motorola’s use of the Quasar brand name, so I’m not entirely convinced that’s a correct match.

If anyone can tell me if this IS actually the correct SAMS number for this set, or can point me in the right direction for additional into (or has a set of schematics you'd like to forward - lol) it would be most appreciated. I know this set isn’t technically "early" B&W, in fact it’s probably one of the LAST models of B&W, as the tube diagram (shown in the pictures) actually shows the tube in the UHF tuner as being omitted, in the “transistorized” version - which this one appears to be.

I also know this TV isn’t worth much, it wasn't expensive when new, it was B&W when color had long since become dominant, it's not a combo anything, and it was probably made in massive numbers. But, it was my parents very first TV, and the one I grew up watching, in the late 1960’s... (We have pictures of me in front of it at age 3 or so.) AND, later on in the 70's, it was converted by me personally, into the computer monitor that I used with my first COSMAC ELF computer. (By bypassing the tuner and IF, and feeding directly into the video input on V3 - later reversed by re-splicing the tuner back in.) So it has some special nostalgia for me. And since I can wield both a soldering iron and an oscilloscope with ease, I think I’m up to the challenge. (Assuming, of course, parts can still be located – that will, of course, be the real difficulty.)

Anyway, thanks again for any input, and for all the advice from previous posters, that will be VERY helpful in starting this project. This is a fantastic forum, hopefully someday I’ll have something to contribute, other than questions!
