The Rokkor lens is typical for a Tessar wide open. Still sharp in the center, dropping off at the corners. Contrast is good.
Best as I can see and have heard, all Autocord lenses are single coated. The lens name changes from Chiyoko Rokkor to Minolta Rokkor by 1960 or so, but I have never seen nor heard that the formulation changed.
I would avoid the 'LVS' model. This is the early selenium meter model, where the meter cell is under a flip-up lid where the name plate is. The selenium is almost always dead. The meter works by giving a number, such as '13.' You then set the aperture and shutter speeds to add up to '13' using the scales on the front of the lens shroud. Clunky! You can ID this model by the larger black where the name plate is located, and the protruding meter block on the left side of the body. The later CdS versions, although ugly as all get out, should be better if you need a meter built in, but I do not know if the meter is coupled or not.
Early models, Optiper MX and Seikosha MX shutters, have 10 bladed apertures. All Citizen MVL shutters I have seen have 8 bladed apertures. I do not know about the transition model Optiper MVL (Optiper is written around the lens, not above the lens). Other than this, I do not think that there is much to be said for any particular. Well, except for the silly strap lugs on the later models, the round post system (you can tap the hole with a 6-32 tap and insert a button-head screw and use a Hassy clip if you must; or make a lug matching the old simple style- just two bolts holding it in place).
The important thing is that the focus lever is free and not gummed up or broken. And overall condition. Beyond that, I don't think any one model has an edge over another. I have a Seikosha and an early Optiper which are going strong, and a mid-era Citizen which is dead from a broken shutter and scratched lenses. At least most parts move from model to model with ease- lenses and such. The cocking mechanism changes from shutter to shutter....
A simple Bay I lens hood. Plastic ,and goes on the inner bayonet so you can't use it with filters-
