New Member from Colorado with a Mystery Tool

[abigalesdad]

Hello All!

I love old tools, mostly found at estate sales.  Some I keep, some I sell.  I occasionally find a tool that I'm unable to track down a use.  Here's the current mystery.  It's about 8" long and the holes seem sized to grip round or cylindrical objects with approximate diameters of 1 1/8", 3/4", and 3/8".  It is made of brass or bronze, likely for either non-sparking or non-marring purposes.   Other than the tags with it's numbers, there are no stamp or casting marks on the device.  It was found at the estate sale of a guy that was a plumber or hvac type. 

I've got a few other mysteries, but I'll do them one at a time.

Thanks!

The type of copper tube that comes in coils is "Type K" soft copper. One of its uses is for underground supplies.

If the end is a little out of round it can be hard to sweat a fitting onto.

This is a guess for that tool, I usually used swage type tools, but the sizes are right, and used with a mandrel of some sort, those could re-round soft tube.

possibly, could also be used to hold the tubing while either reaming the ID or to hold it to run a tapered drift pin to reshape the ID ?

small enough to carry in your pocket as a hand clamp to hold the tubing.

just a thought.
