For lathes? Many of them in a pronounced "S" configuration.....

I've got a ton of these now, some of them quite substantial, 1 foot long,
1/2" thick at the ends.

In principle the same as Sears wrenches, but black iron, really bulky, but
nicely made.
Still, not very practical, it seems. Sears combination wrenches are all I
ever use.

Any value to these? Scrap'em??
