Condition: Used but in nice condition. Now, it seems to work as it took s moment to fire up. Then as you can see in photo #2 an indication light came on and the needle on the Micromhos widow responded. If you are interested and would like to ask me further questions please feel free to do so. It is a great piece of c. 1940′s-50′s technology. It is in beautiful condition and seems to be working to some extent. It even has an additional scroll to use with different sized and strength tubes.
