The build and tube types would suggest late 1930’s design.   Do you know of any source of information about any of the following?

> I have the MI-2877 amp, and discovered that it is 20” wide rather than the standard 19” rack width.  It appears to otherwise conform to the 19” rack standard in regards to height spacing and mounting hole positions.   Do you know anything about a 20” Navy rack standard?  So far I have not found any info.
