Armstrong and other striking wrenches

[FSrepair&fabrication]

I was fortunate enough to have a service call near carlisle PA yesterday so we swung by the truck show to check out the vendors at the end of the day. Alot of guys selling older truck brand stuff for new prices and alot of junk, but i found a set of slugging wrenches in a pile of junk and wore the guy down from $10 to $3 apiece. Yes i know thats such a ******** lowball offer, but the guy was an ******* and wanted to clear out and go home so he took it. $21 for 7 wrenches, mostly armstrong, with a williams and a proto thrown in. That guy didnt even know what they were used for lol

Question is, a few of these are some oddball (to me) sizes so I was wondering if anybody had a clue as to what theyd be used to work on. The 1 5/16 and 1 1/2 can definitley come in handy with truck lug nuts in a situation where i dont have air. 1 1/4 I could prolly use eventually, but 2 15/16? never used that one ever before in a socket or a wrench.

Common sizes for petrochemical equipment. Old school, replaced with HyTorc tools in my plant (but still around just in case).

Good to know, I normally use my 3/4 gun and air when i have stuff that big, but lately ive been doing more plant work and it may be handy for pipe flanges and stuff i may encounter in the future thats out of range for the air gun. Any other common sizes i should keep a lookout for?
