That's for the "How long does it take to remove a rocker arm shaft?" test.
My first thought was for heating paint?
Dude, 11/16 saltus! Well done. Now you just need to find that uncommon 1” and you will really be on top of your game
Oh **** ...I thought I got the "set" if they make 1" did they also make 13/16",7/8", 15/16"?
Your Select Steel wrench was made by Indestro.Don't know much about this guy. 725B seems to be a pretty common model number amongst different manufacturers/brands.
All those kinds of numbers, indicating the opening sizes, were derived from an early Williams model numbering system and were indeed largely adopted by the rest of industry by the 1930's. The 725B is the most commonly found, because that 9/16 x 1/2 pairing was very popular for use. You can find that explanation in the Helpful Hints section of the Sticky on the Vintage Board. You could peruse the A-Z threads list while you're there to familiarize yourself with various brands. And you might want to read through the DOE wrenches thread, especially if you're going to start picking them up in bunches, to see which are rare, which are common, etc, and learn more about markings. Even at flea market prices, they start to add up in space-taking. Unless they're just users, in which case the only thing that matters is sizes.

Your Tru-Fit wrench was a Lectrolite product. Many Tru-Fit wrenches are not marked Lectrolite.
Awesome info and suggestions. Thank you.
Kidding!

Late 30's through wartime up to 1946-ish SK.
All of NB's production in that era, including Craftsman BE/(H), came with that dried BLO/varnish as a rust-preventive preservative. Needless to say, it worked!
