Vintage Crescent 12” adjustable

[Captain Spaulding]

Going through my dad’s toolbox after Mom passed, I came across an older 12” Crescent adjustable wrench. Likely my grandpa’s or maybe his dad’s.

I was struck by how much beefier this wrench is than a modern version.

Was this the norm at the time, or was this a special purpose wrench. Long line of railroad workers on both sides of Dad’s family, if that points to anything.

Anyone have a guess as to vintage? The semi-plated wrench was a road find 30-40 years ago, so I’m not sure of actual age. The photos don’t really do justice to how much stouter the older one is.

Carbon steel, probably. You would be struck by how much beefier it is than a Crestoloy version, made during the same production period as yours, or just a few years later, but with alloy steel. You haven't shown the flip side, but I am surmising that it reads 12", DROP FORGED STEEL, and MADE IN U.S.A. (The Crestoloy variants, introduced in 1930, were marked identically, with FORGED CRESTOLOY STEEL on the flip side instead.)

It's early. 1920's or 1930's. EDIT: I seem to recall some discussion about the "R" marking (and other letters) that appear near the hanging hole on the Crescent thread. One of the early Crescent aficionados may be able to date it more specifically. Not sure.

Learned something new today about the "R". Will have to check a couple of mine.

The width of the head and jaw on the early carbon steel Crescent wrenches is striking. The earliest wrenches are usually marked patent pending and the adjusting wheel is knurled. When the Crestoloy alloy wrenches were introduced the material was much stronger than the carbon steel and the head and jaws were able to be made much thinner with less risk of breakage. I am not aware of any studies being done on letters by the hanging hole.
