Hello all! I am working on a movie in Georgia that involves a scene with a tractor battery charger in the late 60's. This battery charger could be anywhere from the mid 50's to early 70's but I have no idea what to look for or where to look. If anyone has photos, advice, ideas on where to look or one to sell for a reasonable price (it doesn't have to work), I would be very interested to hear! Thank you very much.
