Just pulled a roto baler out of a fence row in Brimson, MO. Serial number is 10675S, 1948. Does anyone know what the S mean in the serial number? I have a 50 and 52, there is no letter's in the serial number on those balers. This baler is in really good shape even though it was buried over the top of the wheels. Should be able to get it going without a lot of parts or work. We baled 20,000 bales a year with a roto baler back in the late 60's and 70's.
