Wanted: GPM3 Parallel Plate Micrometer
I am looking to purchase a new or used Leica GPM3 Parallel Plate Optical Micrometer.
It is my understanding that the GPM3 will attach somewhat easily to a Wild/Leica NA2 optical level. Please email me at the following address (no spaces).

The GPM3 is designed to fit to the current style of Leica NA2. If you have an old style Wild NA2 then that takes the GPM1. The two parallel plate types are not interchangeable.
I am not sure when they started to carry the Leica label. The level I am using was purchased new in 1985 and is definetely not the older style despite being labeled Wild-Heerbrugg NA2/NAK.
