I posted this picture over on another forum, and thought it might make a nice display here, too. Snuggled in the loving arms of my largest (12") outside calipers (Starrett, 1895 patent date but no model number stamping; I could probably track down the model in my catalog, but lots to do today) are, from left to right:
3" Starrett outside calipers
2" Lufkin dividers (my favorite machinist's tool company)
3-1/4" Starrett dividers, a style I can't find in either my 1954 catalog (thanks, Uncle Charlie!) or the current web listings - I wonder when they made them?
2-1/4" Lufkin (yay!) inside calipers, purchased recently after I had to measure a slot for which my existing inside calipers were too large, in a spot where I couldn't put slide calipers
2-5/8" engineer's square, from a set of five made in some unnamed country; useful surprisingly often
2-1/2" adjustable bevel, which frustrates me because it's hard to lock securely; it would have been improved by making the knurled portion taller for more grip
Slide caliper from Brown & Sharpe (my second favorite machinist's tool company); measuring outside up to just shy of 2-1/8", inside to a little larger, and with a 3" rule on the back, it goes in my jeans pocket when I'm headed to the hardware store and expect to need to make a small measurement
