J-36 Find

Recently while browsing the QRZ equipment for sale, I found a Army Signal Corps J-36 made by Vibroplex.  It turned out to be a 1941 Lightening Bug which was diverted into the Signal Corps Morse training program early on in WWII.  It has a serial number of 2145 and was used in classroom training.  Its condition is excellent, after a lot of elbow grease for cleaning.
