Well the Serialization says it was produced with Titanic Steel barrels so it will always remain a mystery as to why the barrel flats are stamped Grade-3.





.

Sorry, the barrels are indeed serial numbered to the action. Had to take a second look at the barrels.

At the time the gun was rebarrelled, all Titanic barrels were probably stamped with a grade 3 stamp. When the gun was originally made, Titanic Steel was used in several grades.

That’s a possibility Bill. Titanic barrels were used on Grade 3 and higher. Acme Steel barrels wouldn’t be produced until 1907 I believe. Peerless Steel I believe was used on Grade-7…





.

By the time the gun was rebarrelled, only the D grade guns were barrelled with Titanic steel, hence the "3" marking.

Is the "3" you are referring to, the small "3" stamped on the barrel flats nearest to the breech end of the flats?

Yes it is Bill...

That is where the grade of the gun the barrels are intended for is stamped. Grade-2 and lower were not stamped there.

My barrel flats are stamped "Overload Proved"---I read that this stamp started to be used in 1925---so my barrels were made in 1925 or afterwards?
The rib of my gun is stamped "Meriden CT"---when was this first used rather than Meriden, Conn"?
Thanks again to responders.

They changed from CONN. to CT. U.S.A. circa 1919.

One other thing if it was rebarreled after 1910 Parker Bros. would have fitted a new bolt and the 1910-style bolt plate on the lug --
