In Reply to: 9n 1941 or 1944 ? posted by ERIK on April 16, 2019 at 08:29:05:
I would like to see a picture of that plate. The serial numbers on the 9N was stamped in the casting not on a plate. As to your question the engine was the same from 1939 thru 1947 in 1948 the serial number would start with 8N but the engine would still be the same.
