I AM TRYING TO PUT A CROSMAN 1088 BACK TOGETHER. I CAN'T FIGURE OUT WHERE THE INTERLOCK & SPRING GO. PART # 43 & 44

Question edited for clarity. It is a Crosman, not Grossman!
Question moved from Motorcycles.

Here is the official Crosman Service Manual

..

why not get and read the manual and see the parts list
and google finds it easy.
or ask the make for parts

its CROSMAN, forgot that key fact no?
1st google hit lands here, ask them we are not them and moved you out of computer repair help.

Hello Willis H DuPont...

Air-guns ... (are real weapons)
like every other gun on the planet are to be treated
with the greatest RESPECT...

Had you actually posted a question here...
I might be able to help ( no actual mind reading ).

What I can do is advise caution, training & mentoring
before proceeding.

OWNERS MANUALS are delightful sources of
necessary information.

So my best advice would be take out all the 0-Rings etc and bring them to a local hardware store and get replacements but also the piercing piece may be worn down.
