Question ? Benjamin Franklin Model 137 Pump Pistol(Pics)

I have restored a old Benjamin 137 .177 cal pistol.Well at least it shoots and holds again.
Was there ever scope mounts made for this pistol?
The barrel is a tiny .314 or about 8mm in diameter.
Sheridan or Crosman are both way to big in diameter so the two piece or one piece inter mounts will not work.
Any body have a idea as how I could mount a small pistol scope to my oldie but goodie.

Thank You in advance!

Were Benjamins originally called Benjamin Franklin?

Great historic piece. Were Benjamins originally "Benjamin Franklin" throughout the lineup? Or was that designation reserved for top shelf models?

I repaired a model 312 pump rifle for a friend awhile back and it also was stamped "Benjamin Franklin"
If I remember correctly it was just a play on words according to Tom Gaylord.

" Yes sir, it does have "Benjamin Franklin" stamped on the left side of the receiver tube, but that is just a play on the name of the company - the Benjamin Air Rifle Company, which you'l find stamped on the end cap behind the bolt.

There has never been a Benjamin Frankin model. Many older Benjamin guns have that name stamped on the side. The fact that the name is in quotes indicates that it's not meant seriously."

Bob, I wonder if the receiver is wide enough to cut grooves into? You might not want to do permanent mods to this gun, tho.

Scope mounts

July 24 2010, 3:46 PM 

Back when this gun was made, the barrels for .22 Benjamin gun were of larger outside diameter than .177 guns. As a result, two different mounts were produced. The mounts were part number B-272 for .22, and B-270 for .177. These should work for mounting a pistol scope just as well as a rifle scope. If, of course, you can manage to locate a pair. They are not easy to get hold of.

When I got my first 1377 I made this up to mount a small red dot, it didn't take long to make.
although I did have access to a mill for the project. I'm no machinist as you can tell but it
worked.
