Here is a Stewart-Warner "Wings" 5,000 RPM mechanical tachometer. It is in beautiful shape & works well. It features the correct curvature glass, a right angle drive & the original split mounting brackets (which are hard to find in themselves). The price is plus shipping, which would be $15 to the lower 48. PalPal would be best, but a Postal Money Order would work, as well. The first P.M. committing to buy gets it.
