Vintage Duo-Fast Pneumatic stapler

Description

Here we have a Duo-Fast air stapler. Not sure of the model number but GC13135 is stamped on it.
This is for repair. The spring that belongs under the trigger is missing. If you push the pin with a screwdriver it operates. But it needs a piece or 2.
Being sold AS IS
