NUKB76 RIBN,TYP,NYL,UNDERWOOD,BK

This ribbon will work in Teletype Model 14 and 15 machines, as well as the later 28/33/35 models. However, the older machines hit hard enough to puncture the ribbon on characters like "-".

I bought two of these for an old '59 Underwood Golden Touch, and for the price they're decent enough. They fit into the ribbon holders. The ink prints dark on the page, though you can see some textural marks on the letters; however, that could be my typewriter; old machines to have a lot of imperfections. At any rate, a good buy. Shipping costs a good amount of cash, so go look in a store first.
