Nick Hahn did an excellent write up of them in the Winter, 2012 DGJ. We (my late Father and I) have owned one since, well, 1964, and it has been a good little soldier.
A firing pin broke early in the gun's life, perhaps the early 1970s, they were a stock item at Ahlman's-my Dad bought two, the second hasn't been needed.
Dad's is a 26" barrel 12 choked mod/imp mod, and he put the dreaded white line pad on about 20 minutes after he got the gun. When the pad was new (and, soft) the single trigger would fail to reset with light loads, but, that went away after I cleaned it and the pad got old and hard.
They are a bargain in today's gun world.
Best,
Ted
