An antique gauge set, I think it’s called a bore gauge; I’m not sure if it’s for measuring holes or other instruments. There are 6 tubes (the longest one unscrews into two pieces, a disk and a gauge. The box is solid wood with a lot of age. The dial on the gauge reads “Intast, Made in Germany” and has different dials. The metal feels like steel. The box measures 9.75 in. x 4.75 in. x 1.75 in.
