#14 wrench?

[oldgoaly]

It says 14 on it now I'm no metric expert but 14mm is about 5/8"  that is the next size down from 11/16ths in most wrench sets. The Barcola is one I found hiding which #14 the other hiding were rusty so they are having a mollasses  bath for a week or two.
So is #14 part of a set? it may have more info under the tar like crap that doesn't want to come off!

if its tar, soak it in kerosene.

I would but don't have any, not sure how well old gas would work? not sure where my bucket of old diesel is?

14 mm is closer to 9/16", close enough to interchange often.

I really like those Convex open enders.

The tar like crap is probably cosmoline, used for preserving steel parts,tools, and other steel items, usually applied right after manufacture, so it has a good chance of being in excellent condition. Kerosene or any Stoddard solvent will remove the cosmoline, but it may take a little scrubbing with a rag. Don't use a scotch brite pad as it will scratch any plating that has been applied to the wrench. Also, never use any gasoline to clean anything as it is very dangerous and can also damage the finish. Plus there are better cleaners out there anyway. Good luck.
