this 55 is well serial numbered
compression tube side
compression tube at transfer port
and barrel block
trigger cleaned of an amazing abundance of grease
I attempted to show that the piston has cocking slots on two sides. sorry for the soft focus.
now for questions - was this a factory adjustment? this was set with some force
there is a white-ish residue on the pot metal parts of the site - how best to remove it?
can I make one of these plumbing washers work to replace the defunct original
as always thanks in advance for sharing your expertise.
