Here's an interesting piece, an outsized display or demonstration model of a Welch micrometer. The thimble rotates to show the numbers on the scale. It's about 30 inches long and about 18-20 inches tall.

Wow that's cool. Welch Scientific didn't make tools per se; they made demonstration models, posters, etc for schools (they also sold labware). I remember Welch stuff being all over my grade school but we didn't have one of these.
Imagine trying to teach kids today how to read a (even rudimentary) micrometer?

Micrometer? Heck the kids today can’t even read avruler!
Our high school chemistry teacher had an enormous slide rule hanging over the blackboard, I believe it may have been a Welch.
"Enormous slide rule..."
I know a guy who collects slide rules, and he wants one of those *so badly*.
I first saw one in the early 70s, and IIRC, it was made by one of the major mfrs for instructional purposes.
