A very nice find! They're never usually that complete and unmolested, and to fire up so easily!! It's the same as my 44 which has absolutely no history attached and took years to find/make all the missing parts. We've seen them dug up after being buried for 40-50 years and rescued from an island after a lifetime of logging.....And you happen to find one under a sheet!!Lucky guy
I'll look forward to seeing what you do with it
