Tuning Need help with identification and parts

Alright so I have my dad's old 1980s Crosman Medalist 1322. It's starting to shoot at random fps and the pump falls out of place. I cannot tell if it's a type 1 or type 2. And finally I cannot find any steel breeches that match the plastic one. If anyone has any links or shops I can visit I would be so grateful. PS the magnets on the loading cover keep the cover from flying back.
