Gents,
According to Stroebel, Savage offered several brand name sights from the factory over the years, sometimes bearing the name, and sometimes bearing a rebranded Savage number designation. The standard rear sight for model 219/220 is called "Savage #20 semi-buckhorn rear sight." It is LIKEY a redesignated sight made by one of the companies they offered.
From the earliest days, Savage offered Lyman sights, either standard or as an option (some guns offered multiple options).
Still early, they offered King and Marble sights, and then later starting in the 50's they began offering Redfield and Williams sights. I dont see any other names in the book.
BUT. I KNOW that I have seen multiple Savage model 340 bolt action rifles wearing Dockendorff rear sights. They all had a circlular disc that you would spin up or down as the riser, rather than the little stepped riser most sights have.
And while the book doesnt mention Dockendorff for the Model 340, it does say that the standard sight for that gun was a "Savage disc-type rear sight."
So...decent guess that Dockendorff was the maker, I guess.
They began the Model 340 in 1949, but it says here that the "disc-type" sight was first offered in 1953.
As such, you will have to speculate as to whether it was original to your 219, or if it was original to a 340 and someone transplanted it.
At a minimum, you know it's a 1950's vintage sight.
On Dockendorff...I dont have a primary source, but on a web forum I see a gentleman who posted the following:
In the January 1948 issue of American Rifleman, page 57, in the section entitled 'Gun Trade Dope,' they note that "Dockendorff and Company of Oronoque, CT" had "introduced their new front sight." And there was an add for it on page 85 of the same issue.
So at a minumum it's at least possible, by timeline, that the sight is original, and the catelog simply doesnt show that it was an option. Heck, knowing Savage, and considering it was an inexpensive gun, they may have just run out of whatever the #20 is and started sticking that sight on for a run...and never noted the distinction.
