First of all DO NOT use regular oil on an airgun, Always use "air gun oil" like RWS or Crosman pellgun oil. Regular oil will eat the seals. You did not state who manufactured this pistol. I'm going to guess 'Crosman."
Oil the hinges, Put a drop of oil in the breech and the barrel to coat the inside. Put a few drops on a small rag and wipe the pistol down. That's all that is needed.
It started in 1946 to 1985
Produced between 1946 - 85 as models 130, 132 and last as 137. Please state the condition of the pistol to get an estimate of value. Poor, Fair, Good, Very good or Excellent.
They were made from 1946 to 1985. If you gave me the serial number I might be able to give you a year.
Benjamin made this model from 1946 to 1985, but did not start serializing them until 1957. I also have a Benjamin Franklin that has no serial number. Before 1957 it is not possible to set an exact date. Just know it's OLD. The 137 is a .177 caliber pellet pistol the 132 is a .22 caliber pistol and the 130 is a BB pistol.
see the link below:
It was made in 1976. It's part of a series of 3 pistols (130 Series). It's either a 130 - BB, a 132 - .22 cal or a 137 - .177 cal pistol.

Which Model are you asking about.
Benjamin made a 137 pistol not a 137 rifle. They did make a 317 rifle, is this what you are asking about? The pistol model 137 was made between 1946-85 the rifle model 317 was made between 1940-1969
To get an answer you will have to state the condition of the pistol & is it still working?
