I guess Casey is not going to tell us how his barrel flat is marked. However, early SC guns were equipped with Titanic Steel barrels. My 177,741 is a Titanic gun. Early SB guns were probably Titanic steel also, but I have not seen one.

There is rarely a time when I fail to learn something from a visit to our website.

I could have made myself clearer. "I have not seen an early SB" is what I meant to say. I assume early SBs are Titanic Steel, like another poster suggested.

Bill I looked at my SBT 178956, made in 1917. There is no steel reference on the rib or in the Parker records. How do you determine the type steel?

Bill, I have a SB made in 1920. Would that be considered early?

The steel type is stamped on the barrel flat. Titanic is "T", Acme is "A". Randy, only you can tell us what the marking is on your B Grade. Does anyone have an early SA that they can check.

Mike, check the barrel flats for a symbol of steel type. Probably a T for Titanic.

Randy, Parker started SBT's in 1917 and they had floral engraving on the trigger floor plate. These are the guns I would consider "early SBT
s"

Good Morning Gentlemen, I checked my SB grade made in 1920. Marked Acme Steel on barrel and "A stamped on barrel flat. Also had three patent dates stamped on barrel flat. I guess now I need to send for a letter to learn more...

I checked and there is a T and also an A. The T is larger so I assume its titanic. There is an unusual looking starburst engraved on the lug. Any idea what that could be?

Randy, when the steel type is marked on the outside of the barrel, it is no longer the "earliest" generation which had no visible steel type stamped or engraved, on the barrel or on the rib. My B is serial number 226,648. What is your number? The Bs are nice guns. I'm looking at an overpriced A, but probably won't be able to get the price where it belongs.
