Audiotronics 300B battery operated classroom record player

Here's an oddball record player that I just obtained - an Audiotronics 300B that looks like other more common classroom record players from the '60's, except this one is battery operated (uses nine D-cell batteries). The amplifier is handwired with TO3 cased output transistors and for the exception of not having a power transformer, rectifier diode, and filter capacitor, it looks like the amplifier in the AC operated models. The drive mechanism looks like it was sourced from BSR and I found a 1966 date code on the speaker. Over the years, I've seen a couple of these on ebay; but, I've never had my hands on one.
