Hi John, was given an Original 50 serial # 1121 last year.
Some pratt had put about 4 coats of thick varnish on it & the trigger guard & under lever catch was missing.
With a lot of sweat I have refinished the stock & made & blued guard & latch.
Looks a different rifle now. Can't make my mind up about re-bluing (which is very indifferent at the moment)
Don't know anything about these rifles (it's a .22)
Out of interest anybody know what they're worth,(I wont be selling it)
