Chrisdt has a point, tissot brand is well known/advertised, expectedly more fake ones out there than genuine.
Tissot licenced, know-how etc are decent colones used by tissot as well.
You may want to post a question to see if it is genuine, if fake you can possiblg buy another one for the cost of repair.
Here is the file rest that I made for a special job. I was going to make the rollers from O-1 and harden them but decided to go with standard bronze flange bearings. These are readily replaceable if i ever wear them down.
Leinen also supplied those micrometer tailstocks on the Henry Paulson lathes that they made. The scale is in mm. To use it, I set the micrometer to zero, insert the required drill in the tailstock (held by drill chuck or collet), slide the drill tip against the surface of the metal to be drilled, slide the stop ring up to the back side of the micrometer and tighten the set screw. This stops the slide movement at the "zero" thereby setting the surface of the metal to be drilled. Next I turn the micrometer to the desired depth of the hole to be drilled. From now on, I can drill as many holes as I want at the desired depth. Picture is of my Paulson lathe.
