M400 #752 prior to restoration. This tron has an interesting white vinyl covering and aluminum trim. I only have cleaned the outside at this point with some Windex, otherwise it is exactly as I found it.
Note the Chamberlin, and the clear and mahogany M-400. Mellotron Archives at that time was in Moses Lake, Washington (State). What';s atop the 4-Track? A Birotron? Looks a little too big to be a Birotron.
