Slowly filling my considerable knowledge gaps... reading through some of the books and forum posts on this, but then following up here when there's another question which comes from that process. much appreciated

No 850-T motors with the generator up top from the factory, only a crank mounted alternator on the front. It looks like yours has an Eldo timing cover replacing the original and an aftermarket alternator kit. There is likely an adapter on the crank to mount the belt pulley.
I'll be doing the same on an Eldo soon that also has an 850-T engine in it. I have a Harper's alternator bracket and ND alternator.

Interesting, again. This is fun for me, "unwrapping" this info, and I appreciate your patient answers.
Attached (I think) is a poor lighting pic from the front. Making sense now.

It looks like someone spent some time, money and love on this old girl. First thing I would do is check the base of the cylinders to see if there's a Gilardoni casting. V700's, Eldos, 850Ts and T-3's all had chrome cylinders. the chrome is prone to flaking. Gilardoni barrels are the most common replacement and the easiest to check for. ( casting mark) Tome T motors came with oil filters.
If it's mechanically sound, I'd find a set of fenders, a seat, handlebars, and a fresh paintjob with some pinstriping and call it a day.
post more pictures!

Touché….
Same list of things was in my head but i had also assumed a lot more engine work, which may now play out differently (better). I knew i’d need to pull a head to see what i’ve got, and may get to that sooner than i had planned. After charlie pointed me in the right direction, i did check the cylinder base for markings, but didn’t see anything. maybe nikasil, or maybe i’ll have to pull them to address the chrome.
Rodekyll has just shipped me a fender, to get things started. And stopped by my painter to check on his schedule and plant the seed for some upcoming work…

You don't necessarily need to pull the head to check what material the cylinder bores are. This can be easily done with a "pencil magnet" inserted through the sparkplug hole and touched to the cylinder wall. Zero magnetic attraction = chrome, very slight = Nikasil, strong = iron liners.
