So far the closest I’m seeing is Kelvinator ER435 and that’s for a service manual from 1954 that can be downloaded (not free) online. https://www.automatice.org/cgi-bin/index.cgi?brand=Kelvinator=RA
If you have the range, pics of it would help, especially pics identifying model and serial #s.
At the same site are posters that might help identify your model https://www.automatice.org/cgi-bin/index.cgi?showdoc~1126~Kelvinator~RA
If you do a google image search for Kelvinator ER434 you come up with newspaper pages with old ads but you cannot see full size pages without a trial subscription https://www.newspapers.com/newspage/17300610/
Finally a google image search for “vintage kelvinator electric range” will give you lots of images. Without pics to know what yours looks like I’m not sure where to start. Maybe you will see yours there.

I was going to suggest the same as MarkBlemish - if you can please add some photos of your actual range that would certainly help.
