Oh look, another clip…
Small taper head lock screw for the pivot bolt.
Then the pivot bolt unscrews.
Pretty standard breech seal. Barrel is an insert in the cast assembly.
Barrel locking lug fits into a cast profile hole.
Rear sight disassembly, remove a clip…
Not a ball bearing detent, a half round pin detent. Neat.
I don’t think that pin on the right is meant to be removed as it retains the elevation detent.
Elevation uses a ball detent. 
Trigger/sear details.
Two small pins retain the trigger and sear. 
Straightforward. The cutout screw sets the sear engagement.
Another ball detent.
All done! Reassembly should be the reverse, will post more if any surprises come up.
Nick,
ReplyDeleteThank you! I am into the older airguns and really enjoy seeing how they are put together.
