Recently picked up this huge wrench at an antique shop. couldnt pass it up for $5 i have no idea what its for. it does have some numbers stamped on it (8E50) and it looks like the last owner simply used it as a hammer.

Is it a lug wrench? What is the drive size?

It does kinda look like a lug wrench. It's shaped like a lot of lug wrenches I've seen, anyway. I'm also curious as to the drive size.

Looks like a generic lug wrench that came with an old car or piece of farm equipment.

The Drive size looks to be either 1"5/8" OR 1"11/16"
