HW/Weihrauch HW90 Locking up

Recently acquired early series HW90! During the cocking cycle when RETURNING barrel into closed position it jams on the return. Check the stock screws, no interference, seems to be the chamber and the bottom of the breach block rubbing and locking up

Anyone else have this occur and know solution please

No expert but I'll take a stab at this ..

First looks like a older gun so maybe look at the cocking arm gliding piece
( Just its name kinda clues ya in ..lol)


Sold separately as well



Next I'd look at the cocking shoe..

The old shoes get worn in the tube slot and become I'll fitting and can bind and scrape ..

Old .


New ( now.. don't know how straight forward swapping out or what extra involved with the gas ran gun ) .p.s. Old style can be hard to get or a no longer available item as well ..
