Biggest Wrench ever?

[DT86]

I've had this thing for several years. I got it from my Grandfather. IIRC someone gave it to him, He had no idea what it was used for and neither do I. Any ideas?

BTW..It says "BLACKHAWK MADE IN USA" and "MAX 4 1/4 inches"

It comes up to the front pocket rivet on my Wranglers, I'm 6'1"

Shown is a 16" Craftsman wrench and a Sthil 290 Farm Boss for comparison.

It's just a wrench. I've seen large nut and bolts used on turbine housings that wrench would be used on. Not for final tensioning though. The bolts were hollow for a heater rod to expand the bolt. After cooling the bolts would contract tensioning the fastener.

Just a wrench? No s**t Sherlock.

I'm thinking it has some age to it but what do I know.

You can buy one that looks very similar new from OTC. It's supposed to replace several size wrenches with the one as large wrenches are generally pretty pricey though these aren't cheap. OTC 7641 Adjustable Wrench First one that popped up on google.

Alright alright maybe it's not rare but does anybody else have one in their shop? D**n here I thought this thing was cool enough to share. I must of been wrong. lol

Edit... For those it was lost on, the title "biggest wrench ever" was a joke. I know there are much bigger ones. This is my biggest one.
