Hi Paul,
Congrats on obtaining a well-kept vintage "floor-type" G-E vacuum cleaner! I would imagine that if there is no ratings plate, the information was stamped somewhere on the nozzle.
Here's a list of model numbers of G-E's AV/AVF Series (American Vacuum - Floor?) that I found online - mainly using a periodical database or mentioned on VL. I was unable to find an ad with a line drawing of your model - going mainly by the bag graphics. Most ads omit model numbers, so the years below may or may not relate to actual production.
AV-1 1936-
AV-3 1936-
AV-5 1935-1942 (VL thread)
AVF-18 (VL thread)
AVF-19 1942-53
AVF-25 1943
AVF-26 1947-52
AVF-28 1948-54
AVF-55 1942-43
AVF-101 1943
AVF-801 1949-
AVF-804 1951-
AVF-807 1951-55
AVF-812 1950-

AVA-808 attachments
I'm uncertain how the model 800s features differed from the those of the lower-numbered models. I did read on a couple VL threads that some models were either updated or had different versions, indicated by letter suffixes in the service manuals, if not on the cleaners themselves. At one point, G-E had several concurrently-marketed uprights with different price-point features; but I was unable to locate further details. Some models may have been promotionals with short productions.
Below are some of the ads I located.
