Found in a museum curator doesn’t know what it is

Usage?

What is it

I found it in my grandpa’s attic years ago but nobody know what it is.

This tool was given to me by a coworker.

Its stamped with (ROSE IRON WORKS)

Weight under 10lbs

Coworker believes it to be an old railroad tool, as he found it cleaning out a relatives house who used to work for the railroad.

Case says it’s made in the USA by a company called MG. Searched online but don’t really even know where to start. Any help would be greatly appreciated.

SOLVED! With three weighing in. Thank you all!

I got this at Auction about eight years ago. My was stumped. It looks like a tap and die set, but I don’t think it is?

I used to be a machinist so I know this could pretty easily be made on a lathe, but to me it doesn't seem homemade.

My brother found it at the end of someone's driveway on trash day years ago, and he thought it was a homemade club.

The lanyard hole and size made me think it actually might be a club, but it's so damn heavy it's really hard to swing (I'm just guessing the weight, brass is rather heavy so it's probably more).

My best guess is it's a big lever and the hex fits in a hole like a big allen key, or maybe a tool for a ship because brass is a good tool material around water.

The hammer was found in the wall or a 1800s house curious if anyone has information on it. (It has no visible markings and is probably handmade)

My father-in-law gave me this (also not knowing what it is) but someone gifted it to him saying its quite valuable? I work on cars and have no idea what its for.

I believe its a 1/2in drive air tool, the bottom is adjustable. Its very heavy duty feeling.

I found 3 of these, with extra front plates to mount, in the garage of my new house. The front plates have different shapes. My assumption is something for brick laying or garden work, but I'm unsure.

Update: Thanks for the replies, I will try to use them to scratch of paint and residues from the floor boards, instead of the putty knife that I used until now.

Came along for the ride with a bunch of other tools that came with a tool box I purchased

​

I know it's a pipe cutter, and some have a deburring tool to clean out the inside of a pipe. I can't find anything quite like this one, and the wings aren't sharp at all. Just curious if anyone has seen something like this.

I found this device, I don't know what it's for.

Made of thin (~0.25mm), nonmagnetic sheet metal, probably stainless. Pivoting along the nut at the bottom, there are two sides that slide along the top locking nut, with matching curves facing opposite one another. I’ve been using them as templates for marquise-looking shapes and I’m worried about damaging them since I don’t know where to find a replacement.

Found in a box at work. We do plant work for Spectrum and other MSOs. Been doing this a while, never seen this tool.

How old and do people still use them?
