need help with Benjamin air pistol

[kayateyellowsnow]

while digging through the basement, I found an old Benjamin pump type air pistol.

It pumps, but does not hold air.

I know nuthing about air pistols... what should I be looking for?? As far as I can tell, it is a 130 model. Crossman bought Benjamin, I looked at the Crossman web site, found a crude schematic... but Crossman no longer supplies parts.

Possibly a bad seal or O ring. Once broken down, the problem can be better diagnosed. Some auto parts stores or hardware stores will have parts that will fit. I repaired an old Crossman pump air pistol with O rings that were manufactured to replace O rings in bathroom faucets.

Glock Fan is right on with his suggestion. Over time the seals get dried out, turn brittle and then will allow air to escape past the piston/reservoir. Google and see if you can't find a repair kit for you gun.... Link Removed
