Then, what is it called on the M-21? I have 4 and the book. The male V and the female V extend from the top of the barrels to the bottom of the lugs.

Here are the various ways of joining barrels as described by Burrard:



Fig 4 is "dovetail lumps", Fig 5 is un-named Fig 6 is "through lumps" and Fig 7 is "chopper lumps".

Here is a pic of "dovetail chopper lumps".

I guess it's called a dovetailed chopperlump but I steadfastly refuse to ever call it that again for no other reason than to try to retain what little I know safe from confusing terminology.

Thank you. As I know, the M-21 uses dove-tailed chopper lump construction. They, at Winchester, were simply copying a design already used in Britain.

Those wishing to pursue the question should have a look at p. 131 of MacIntosh's Best Guns. Compare the plan view of the M21 "dovetail" in photo top of page w/ fig. 8 above from Burrard. Note that Mac's caption refers to the joint as a "dovetail". It is however, not identical to the true dovetail in the Burrard illustration. The Burrard joint resists lateral separation and sheer and would do so without brazing. The M21 joint would not resist sheer in the absence of brazing. The identifier is the same; the joint is formally and mechanically not the same.

The gun is one of the very last under lever snap actions built by Boss. The two serial number guns previous to it were top lever ejectors. Boss was building, at the time this gun was constructed, fluid steel barrel, hammerless ejectors.

That is why it is a bit out of period. jOe, the things you are missing we can't help you with here. Have you even READ the ad?

Best,
Ted

What do you mean that it is not identical? P131 clearly shows the dovetail starting on the far left and ending on the right of the second screw.

Good catch and good eyes. Apparently I mean that I am mistaken and have not perused the photo well enuf to know what I'm talking about. It is as you say a full dovetail. I retract my statement above; the M21 dovetail joint is identical to the illustration from Burrard so dovetailed chopper lump it is. Mea culpa; mea myopia.

Thank you. I do not respond to many of these posts.But I do work on many of these guns (a hobby) and I notice that many quote, but have never been there. Watch out for Miller as he will look it up and has been there. I do respect the opinions of the board.It is nice to be in the company of gentlemen.

Ted I did read the add. I don't recall learning from the add description that Boss was building Fluid steel in 1888 ?


If they were building fluid steel barrels in 1888 I'm sure it was not for many years.
I do know most all makers were building Damascus Hammer guns long after 1888.
I'd be curious as to when the last under-lever thumb latch was built ?.

How many years do you think it takes to put a gun "out of period" ?...(as you called it).
Ted...You might want to go study your periods.
