Thank you everyone for your responses. I think I'm going to agree with the posts that this is a cylindrical square. And most likely shop made. The four holes may have had a obscure use specific to the shop.
The thought did cross my mind early on.
What is this cylindrical metal thing found with machinist tools?
I recently bought a few machinist chests full of tools and other goodies. I'm not a machinist myself, but I'm familiar with a lot of the tools associated with the trade. This piece is a smooth solid steel cylinder with four equal spaced holes bored completely through it. It measures approximately 5.5" long and 2.25" diameter. Weighs almost 4-1/2 lbs. The end has stamped "Feb. 48 Eddie Champ." The other end is identical minus the engraving.
I suspect it might be a cylindrical square, but I've not seen examples quite like this. It came with a plastic sleeve.
Many years ago when I worked at Burger King, we had a regular customer who would order a cheeseburger with extra extra extra onion. She was a very sweet older lady, so we always obliged. We piled two inches of onions on those burgers, easily enough for 8 normal burgers. It was weird to all of us, but she absolutely loved them.
I had the same problem with not being able to see comments, even in my own thread. I found that the issue was with the language I selected in my settings. I was told to select 'Undetermined' but I think this only let me see other undetermined posts and not those who have theirs set to English. So I clicked the big 'X' next to them in settings (deselecting any language) and now I see everyone's comments. Hope that helps.
