This is a follow up to my post on the Alco MSM-5a from about a month ago. This is an unexceptional mosaic readout display but the major differences, that I can tell, between this and the 5A is that this one is a little bit smaller, it cannot be easily disassembled and it includes a red filter to color the display. These were purchased from Surplus Shed for $2.50/each.
