Back in about 1975 I bought an Ithaca 37 shotgun. It was a factory knock off of the ones used in Vietnam by the seals. Parkerized finish, 20" barrel with a 1-piece magazine tube that held 7 rounds.
I had an adaptor made so I could attach one of the duck bill diverters. In the process I found that the latest diverter was actually a figure 8 or infinity diverter. I had that added instead.
I traded the shotgun away about 10 years later and then traded for it again after another 5 years. After I had it, I noticed that it had been abused. Someone had fired steel shot thru it and had somehow managed to force a pellet (#7 shot)thru the side of the barrel about 7" from the muzzle.
After buying a new barrel, cutting it down, removing the vent rib, and moving the lug out to the end of the barrel, I'm happy to announce that my shotty is back!
Now I need to reparkerize the barrel and possibly locate a synthetic stock.
A little more on the diverter: It looks like an infinity sign or a figure 8 on it's side. I no longer have a circular pattern, but a rectangular pattern. It is a 4-1 ratio. It's 4 feet wide and 1 foot high at about 15 yards if I remember correctly. I have to pattern it here pretty soon.
