Does that say MADE IN USA on the rib? The book lists it as 32'' bbl and straight stock so that hasn't been messed with.

what is the usual butt configuration on a SBT?

Recoil pad.

Question: Were there ever any SBT's made with the typical shotgun or pistol-grip stocks? I remember shooting trap with a fellow YEARS ago who shot a Parker single barrel, and I'll be darned if I can remember the stock configuration. I'm pretty sure the gentleman has passed on, and I'd like to know whatever became of that gun. He shot it well...

Yes, they were made with straight grips, pistol grips with caps, and pistol grips with round knobs instead of caps. This gun should have a "T" on the barrel flat indicating Titanic Steel for the barrel, as well as a weight stamp with a number for pounds and ounces. Nice gun.

I thought the lowest grade SBTs were made in was SC (I have one and really enjoy it) with an Acme steel barrel. I have never heard of a Titanic barrel on an SBT but I may well be wrong. If so, I'd like to see a picture.

Yes, the gun is an SC Grade. In his serial number range, it should be Titanic Steel. I'm sure he will tell us what the mark is on the barrel flat.

I thought the C grade had Acme Steel barrels, even the SC

Does the forend have the reinforcing rod or bolt (the head of which can be seen at the nose of the forend)?

We are waiting to hear from the owner to tell us what mark is on the barrel flat.
