81349 is the manufactures code. As soon as I can reinstall a bunch of files, I can tell you who this is, or you can look in the internet.
M5086/2-10-9 is the part number. As soon as I can reinstall some files, I can give you the specs on the wire. The long and short of it is its aircraft grade wire. You simply cant get anything better. Do you need it? I don't think so. The first 30-40 of the MWO's, (Modification Work Order) I installed, we used wire out of the LAWSON kit. Its cheap automotive wire. Works just as well. Then I ordered one of each wire type listed below, 500 foot roll. I used that for the next 8 years, and didn't use it all.
If you need the NSN's, let me know. I KNOW if you plug in the part number in your browser, lots of company's will come up. Stuff aint cheap, but like I said, simply the best.
Better yet, the gen set you took pictures of, and sent me. Use some of its wire harness.
