Quoting the product description from 1981:
"10-pc Tool Set with square recess screwdrivers for recreational vehicle repair."
"CONSTR: Blades hardened and tempered steel, Plastic handles."
9KT45114-Wt. 11oz. $5.99
Another version, 9KT45113 had half nut drivers, no clutch or robinson for the same money. This kit was 45111 in 1976.
Further states imported, but, 1976 and older catalogs don't say imported. Also no robinson/clutch bits. In those days, if COO or imported was NOT stated, it was a guarantee it was made in USA. I dont have 1977 to 1980 catalogs, and I suspect that is the time period of your set. The pouch and tray match the poor black and white drawing, and the metal snap on your pouch and the =V= embossed on the handle fit the time period. Color photo in the 1982 catalog looks like the snap could be white plastic. Hard to tell. Big price jump too, to $6.99.
Collectable? Maybe, especially to those who go nuts over =V= period stuff. I purchased the bulk of my tools in th 1970's and 80's. Uncommon to rare, especially in the condition of your kit. To me, kits like this were the like the kits from the discount stores, so, I never bought one. The 45111 kit was described as suitable for electronics repair. Not durable enough for my purposes at the time, but, that's just my opinion. Must have been halfway decent. They stayed in the catalogs for years.
Good luck selling
