I "think" what you're callin spud wrenches PJ are likely just a cuppla miscellaneous wrenches that problee came with some sort of equipment or machinery as standard issue tools from the manufacturer.

I have a buncha old double open end wrenches and a pretty decent set of single ended open end wrenches like the ones shown that I've pilfered from mostly German equipment tool sets over the years. These wrenches are really well made and go from 10mm all the way up to 52mm's. The Germans make some really fine tools and these are all near or over 50yrs old now without any appreciable wear on any of 'em!

When I think of a spud wrench it's usually a crescent or an open end wrench on one end with a tapered punch like handle on the other end. These are usually old iron worker wrenches used to line up mating holes in beams for rivets or bolts and then when usin bolts, to tighten 'em too.

I have more than a few pretty unusual tools I've been thinkin of takin pics of and see if anyone can tell what they're for
