pgmrdan --

George Scherr was a New York based manufacturer of optical comparitors and apparently also made some precision measuring tools. They eventually merged with the Tubular Micrometer Company, which made micrometers with hollow frames rather than the forged frames other makers used. (The hollow frames were substantially lighter than even skeletonized solid frames.

The merged company is still in business today in St. James, Minnesota under the name Scherr-Tumico . . . Tumico from TUbular MIcrometer COmpany.

I've got an inside mic set by Scherr-Tumico (8"-32")that I like as well as the smaller Starret set (2"-8") and the Brown and Sharpe sets (1 1/2"-8") and (8"-32") that I have.I use the S-T's instead of the B & S set.
Don't know if this answers the question,but I like them just fine and would buy more if I came across them.Of course,I've never looked at the name only,rather the quality.
Robert.

I have 2 Scherr-Tumico mics, a 5"-6" and a 7"-8". Both are always on the money when I need them. They seem a little funny to handle. I'm used to the solid frame mics.

I have a "Tubular Micrometer Co" 2,3,4,5" replaceable anvil set, reading to 0.001 only. Has a chromed body, and is really light. I'm not sure that is an advantage.

It honestly looks about as good as a "General" micrometer, only a little cruder as to the thimble. Now, from what has been posted, to be a "Tumico" only, it seems that it must be 60+ years old, so maybe that is a point.

On the other hand, I have a Tumico tenths dial indicator which is really nice.

When I ran the big machines I always specified Scherr-Tumico micrometers when I sent my helper to the toolroom.

In the larger sizes (above 18") tubular framed outside micrometers are significantly stiffer and provide a more positive and distinctive "feel". Their bright nickle finish absorbed less radiant heat when working in the center bay with strong sunlight coming in the clerestory windows.

Interesting...this one has a "feel" like a ball of wool. need a torque wrench (light one) to always apply the same torque and get the same body deflection

I have the old Geo. Scheer mics. Oldies, they still do the job. Scheer Tumico mics are also good, have a few in my shop, specialty types. Blade mics I believe, and a thread mic.

I have a large number of Scherr Tumico plunger type dial indicators and a mic or two and all are first rate. I also have a 30" optical comparator that is a Scherr-Tumico, again a first class instrument. A good American company still in business.

I purchased several Tumico mikes from VME. They came in original boxes 50 or 60 yrs old.
They seem to be nice as (or nicer) than my old Union Tool mikes. They get $20 to $30 for them. I feel like that's a steal.
