I just obtained an old 6/8 volt battery charger with a small Amoco badge mounted to the front of it. The tag on the rear of the unit says it was manufactured by Franklin Transformer and it is a model 41. This unit is on wheels and measures approx. 40" high, 20" wide and 16" deep. Can anybody tell me anything about it such as what years it may be from, rarity, or value? It is very straight and solid and would be a fairly easy restoration, I can email pictures if it would be helpful to find info on it. It is missing the circuit breaker on the control panel. Does anybody know where I may find one? Also the meter guage panel is corroded, does anybody know who or how it can be restored? Thank you for any assistance.
