Tang indicates 1955 to 1988 but I'm sure it was made around the late 50s to early 60s.
The celluloid shells are in great shape, I wouldn't have bought it but they looked really good. I asked several questions and the seller was very upfront with the imperfections.
Blades were a little discolored but I think they will clean up good enough. I used a Cape Cod Cloth on them and took some ScotchBrite to the inside of the springs and the bolsters. Then used the Cape Cod on the bolsters as well. Gave the whole knife a good long drink of oil over night and you wouldn't believe the gunk that came out of it. Both blades snap like crazy now!
Wish I had taken some before pics but here's the finished result so far. Thanks to Dale's and others posts concerning cleaning and getting the snap back to this old beauty!
The Imperial Jack knife, 3 inches in length. The funny thing is this knife was probably around a $1 new,,,,
