That's a military acceptance mark. It is an eagle with a letter and a number.

What they said^^^. S&W still had WWI production barrels in stock and used them to assemble commercial Model 1917s clear into the late 1930s, probably later.

Anyone have a spare plunger and spring to complete the lug?

Sacriledge to some...
But I used this barrel to complete this 1917. It is from the Brazilian contract and in roughish shape. For now, I will use the plunger and spring from the original barrel to complete the conversion.
I like the 4" skinny barrel combined with the 45 ACP revolver.

Another Question
I spent a bit of time going over both of these barrels. One thing I noticed is they both have 6 lands and grooves. I thought all S&W revolvers used an odd number (5) of lands and grooves? Did I miscount?

IIRC, it should be 5 lands and grooves.

That's what I thought but each time I count them, I get six! I will look at them next week and try again.

Okay, I looked again and get 5 lands and grooves in the 5 1/2" barrel. I still get six in the 4" barrel. Not sure but I will give it a good scrubbing and try again.

An S & W barrel that has been bored out to a larger diameter, or another maker's barrel of similar configuration to an S & W (front locking lug), would be my guesses.

I never gave the rebore idea a consideration and I have done that with a M28-2!
But this photo is of another barrel so that means there are at least three such barrels for the 1917. And the two I have both have the SA stamp on them.
I am beginning to believe that S&W made at least a few with 6 lands and grooves. Perhaps someone more knowledgeable can offer an opinion or share some facts.
I doubt the idea of another maker because the barrel stamping is very much identical to stamping on other S&W barrels from the era.

Hello Lazarus!
Sometimes, I reread my old threads to remember. Today, I reread this one
WHAT A DUNCE!!,
As I have since learned, all 1917s were rifled per Government specifications. S&W had no say in the matter. And that rifling worked so S&W continued to use it until at least the Model 625-?, or the model 325.
Yes, I can probably blame lack of coffee or too much wine for not being able to count to 6!

Also, the 45 ACP barrels have 1 in 16 twist, where most other S&W barrels have 1 in 18-3/4 twist.
