This is an original Jaeger Tachometer #RN 2300/01 as used on all 1500, 1600 and MKII MGA's.  It still has its original hold down bracket and thumb screws attached.  The face plate does show some fading in spots (see photo) while the chrome trim ring and glass are in great shape, as is the indicator needle.  The case is in very good shape overall with some surface rust in spots.  I was able to test the tach using an temporary setup of a short section of cable and a variable drill.  Needle did move as expected and I cut off the test at 1500 r.p.m. due to the improvised setup.
