We own a 1973 M/B and I have some of the history on it. I know that it was at station 58 in the Bronx in 1973 and it was sold to Maple Shade NJ adout 1984. Maple Shade had it referbed at least 2 times. We purchaced it from them about 1995 or 1996. If anyone in FFN knows more about this unique piece please let me know.
