Authorized reproduction of the Montgomery Ward / Signature dealers servicing manual for their sewing machine models 259, 260, 275 and 276. This is copied from an original which is rather detailed and full of great information. It has a bit of operating information for the machine user and detailed servicing information too! Their model numbers in my experience begin with a UHT or URR. I was told that only the numbers which follow those letters are of primary importance in the model information, by a MW salesman, many years ago. He also said that the difference in the A, B, and C etc. after the numbers is trim added to the machine or perhaps the color of the body of it. (Or in other words; a cosmetic change.) The URR and UHT (universal home table) refer to whether it is a machine in a case or is in a table/cabinet.
