A good friend has the old catalogs, and found this:
"OK Charlie, here's what I found - Your knife is a Landers, Frary & Clark
model 22125 3/4 and it was not in my 1914 catalog which had both H&B and LF&C pocket knives. The next oldest catalog I have is
1919 and this is where it
first appears along with the 1922, 1926 and 1931 catalogs. If there's a catalog between 1914 and 1919, I've never seen it. I've attached an image of page 37 of the 1919 catalog.
The key to identifying LF&C knives isn't the tang stamp nor the etch but rather the pins, shield, covers and blade configurations. According to the catalog, your knife has cocobolo handles, a fine glazed blade finish, brass liners, is a barehead Jack with a single iron bolster (can be verified with a magnet), 4 nickel silver pins, a large clip main and pen secondary blades with a pinned nickel silver shield. The tang stamp and etch are 100% so you have yourself at least a 106 year old New England knife, possibly a tad more. The cost in 1919 was $14.40/dozen which in today's market is $267.74 or about $22/knife - a true bargain!"
Here is a picture from the old catalog!!
