I haven't had my 15-91s that far apart, but it appears that your machine may be a 15-90. I have a 15 that came with a 15-88 manual, however it had a motor and small hand wheel.
I'm thinking that the machine could have been put to use without a complete disassembly. Some would be needed to get he metal bits cleaned and polished. Most machines just need maybe a little kerosene cleaning and fresh oil to be put back in working order.
The decals look pretty good to me. I would polish with TR-3 unless the shellac is compromised, which it doesn't appear to be. Many have benefited by following
