I don't know if that's an owners name or makers mark. Also, I'm wondering if it's broken. It looks like the end has been welded or something. I'm thinking it's supposed to have a cutting wheel there?

Someone will come along and tell us it's a glass tubing cutter (in particular the tubing used in sight glasses for boilers and suchlike, where you have to cut to a specific length), but until then, I'm arguing for a tuning fork for bagpipes.

You're wrong Houghton, ABSOLUTELY POSITIVELY WRONG!

That is a chanter trimmer carried in the Pipe Major's kit.

It is often misused for cutting glass tubing, particularly Pyrex tubing which supposedly must be scored from the inside.

Looks like a tool for performing a "bris"

Oh, the abundance of possible comments; And yet it would be so wrong to give PawPaw a heart attack this time of year. 
Naw!

Huh.  I hadn't thought about tuning the chanter by trimming it.  What do you do when it's pitched too high?  Is there a tool for putting more length back on?

We're being of utterly no use to poor Bird here, who's just trying to figure out what this thing is so she can describe it accurately on that auction site named after a water feature; which will be a great service, unlike so many sellers who get a little plotzed/stoned/somethinged and dream up a possible name for something and try to sell it that way.

From page 73 of Field Expedient Pipe Repair by Sgt Shamus, upon determining the need to lengthen the chanter send forth innocent appearing young pipers to swipe some clown's bamboo fishing pole and a bedsheet from an unguarded laundry line.
Determine which joint of the pole is appropriate in diameter and saw it from the pole between webs.
Heat a sufficient quantity of Spruce pitch at the campfire while a couple young lads sever the sheet into strips ranging in width from 1 to 2 knuckles on a drummer.  While the drummer is occupied borrow one of his sticks of appropriate diameter to act as a mandrel aligning the bamboo and chanter.  Slather generously the mandrel with sheep grease before inserting into the chanter and bamboo.
Glue the entire assembly except drumstick liberally with hot pitch, and dip pitch onto the torn sheet as you bandage the assembly together.

When all is cooled and dry, remove the drumstick gently and place where the drummer can believe he dropped it.

Shorten the bamboo in small increments to obtain proper pitch, and tell the bloody piper to make up some lacquer to cover the new assembly and rub it to correct luster.

I strongly suggest you print the above because the field repair manual hasn't been reprinted since 1937, and copies are hard to find.
