Mr Flectcer,
Would you have any information as to who made the 101 original pump cups for Crosman? Crosman is no help!!!

Wish I knew. I had no luck sourcing this part.

I know Ron Sauls went after this but don't know if he ever had any success.

It's been years since I've looked at this so it might be worthwhile to check in with the various airgun shops. Maybe somebody has made progress.

check with Rick @ Precision Pellet. I know he has been having a lot of the old parts re-pro'd.

I got a bunch of Crosman 107's & 108's and each one has different chrony readings.
Thinking pump tubes might have to be honed out with steel wool? (like honing the cylinders on an engine when installing new piston rings)

John at JG Airguns had a bunch of different diameter leather cups made up- give him a call OR
find someone on the Island who messes with leather (Any Tandy Stores still there?) and discuss the project. You can make a die from stacking washers, then form the leather cups yourself-

I've been told that the Coleman lantern pump cups work for the Benjamins.

Did a search on --Pump Cup 21/32"-- and it turns out this is a common size for carburetor pumps. For example:http://www.carburetor-parts.com/Acceler ... _1078.html

Looks pretty close.

That's a great find! It's not entirely the same as the drawing but it seems as though the Rochester brand is a big clue...from Wikipedia "The company began as the Rochester Coil Company founded by Edward A. Halbleib in 1908,[2] becoming the North East Electric Company the following year. In 1916 the company was located at 348 Whitney Street, Rochester."
