No markings.

And while we are at it, I got this trammel, also no markings. Look familiar to anyone?

They are both for sheet metal work, I believe. I may be wrong. In the first picture the hex looks to be upside down, but in the second pic it looks right.
The last picture, obviously for laying out circles and holes in sheet metal.

They look a lot like some of the tools the sheet metal guys used in the last mechanical contractor shop I worked at. They made all kinds of duct, air chambers, etc. Lots of scribing and such before cutting up the sheet stock.

I have no idea what company produced them.

Must be an illusion, all I did was turn it over. The cutter has 3 points. Sheet metal work makes sense, it came with a lot of machinist tools. I always find it odd when there are no markings on a tool whatsoever.

If they came with machinist tools, there’s a good chance the machinist made them himself/herself.

The first one looks like someone used a hex key and made a decent scriber out of it,I would love to have one like that,just don’t drop it on your toes.

Yes, on the homemade comments. Shop guys are notorious for it. Tool-makers, pattern-makers, and millwrights. I’ve accumulated a few orphans and they serve me well for set ups and milling.

To me, the marking gauge looks old. It came with another hex bar that is similar in length, 12”, but isn’t tapped and threaded on the end so it can’t hold the cutter. I suspect it was an extension and maybe there is a piece missing that connected them. It is a mystery. The head is non magnetic and at first glance looks like stamped metal but I believe it is cast bronze. It’s very cool looking but I’m not 100% sold on keeping it. The trammel I have no use for and will probably toss it on ebay. Thanks for the replies everyone.

You can make a pencil holder for the trammel so you have a trammel point for the center and the pencil to draw the circles. I have a vintage one like that, also probably shop made and it works well for laying out large circles. But since I rarely do that I don’t get much use out of it.

Good idea but I already have a beam compass which I’ve used once, ha.
