Stewart-Warner R-390A

Here is the Stewart-Warner that is currently undergoing restoration.  The meters are not original, but are some of the best replacement meters that I have seen.  It has been completely restored, and I have spot-checked the sensitivity and seen readings near 0.1 uV.  I expect this one will have numbers from near 0.1 uV to no more than 0.25 uV.  I will post the sensitivity numbers when it is finished.  Click on the image below for a larger view.
