how do you read this vernier

Using the second photo as example: the 0 of the (sliding) vernier scale is just shy of the 6mm mark, so there are 5 full mm. And then check where the markings on the main scale and the vernier scale line up perfectly. This is the case one mark left of the 9 on the vernier scale. If it were exactly on the 9, then the total reading would be 5.9mm. But because it's one mark left of the 9 and each of those marks between 8 and 9 is 0.02mm the total is 5.88mm.

Etched or printed numbers and lines?

Etched. This is a surprisingly high quality tool for the price. Do you know how to read a vernier?

How long are the external jaws?

40 mm for the outside reading, 16.5 mm inside reading. The precision cutout at the end is 9.5 mm long, and the steel is 3 mm thick. These are quite typical measures for calipers of this type (i.e., they are identical to my digital-scale calipers).

This divided into 10ths of an inch, then each 10th into 1/4ths ? Each inch is broken into 40 segments.Mitutoyo is only in 16ths. How do you read this?

This caliper measures in 1/1000 of an inch, not in power of two fractions. Each segment is 1/40 = 0.025 inch, and the vernier scale reads from 0 to 25 (0 to 0.025, really). As an example, the 3rd line past 1.1 inch gives you 1.175 inches (1.1 + 3 * 0.025), and the vernier scale gives you the rest, if the lines match up at 12 you add 0.012 to the result you got from the regular scale, 1.175 + 0.012 = 1.187.
