I bought a 54 second hand in the late '70's,it was a real pile of crap,massive and heavy and used to spit bits of piston washer out of the barrel,it also had less power than my meteor.It was second hand and probably already knackered.I bought a brand new 55 in .22 and that was out standing.Not the prettiest gun but a good solid performer.This one counted for many squirrels and pigeons.
