Need one but don’t know proper name?

Sry this isn’t antique but I need one and don’t have a name for it. I’d call it a layout gauge but I can’t find one like it by googling that term. “This Old Tony” uses it to guide his scribe when laying out machining guide lines on metal stock to be milled. I copied the photo from one of his excellent videos on YT. I’d appreciate someone finding either a correct name, a commercial source, or both. Best photo available:

 

Are these like the part you need?

Think I found one and ordered it, first time using Ali Express. $16.27, I used the newbie $3. Discount.

 

Thanks, yes, thanks, now would you mind educating us a bit on the method? I’ve tried using Goog images in past with very limited success so obviously I’m missing something!

 

Wish there was a trick to it but I just googled using sliding ruler gauge or something like that and looked at images. Just lucky

 

Ok, makes sense, I didn’t think there was enuf of an image there to do reverse image search, that image would probably retrieve lots of hands and gloves. Looking down the pages of choices, this one looks closer to what Tony used as it has dual scales on opposite sides, Imperial and metric, so I ordered it too, since I need one in home shop and one in the large shop.

It reminds me of a husky sewing gauge. Not that I sew much.

 

This is a "trusquin" in french, it's current, I have two different in my workshop and use them everyday on wood or metal, the wood ones are made of wood and are slightly different.

 

I've search a translation of the word trusquin but in english they are at least 4 words to translate that, but in a tool catalogue I've found the better one :
Metalworking Marking Gauge
They are certainly metal workers on the forum who can confirm that is an european design you show us, when looking american ones they are like the Starett, but I've never seen this design here for metal, only for wood with a direct point included in the tool.

If you want to buy an old one there is near always a problem, the under part of the head is very often recessed due to years of use, I've changed one of my longer item, it need some time to be really precise(less than 1/10 mm.) and you have to temper it to harden, if you want as I think for use, a new one is the better solution.

 

Thanks, for unknown reasons one catalog retailer here “Lee Valley” calls these “stop rules.” I’ll see if I can get the exact page linked, they are sold out of the smaller size my Machinist friends want, backordered until May, but there are other sources and I now have two different ones on order.

A very good version, and not expensive, I've not found this translation but it' seems it's the good one.

 

I heard that term from sheet metal workers as well.
