HiYa Gang-
This issue has to do with the oil filter housing for the N-Series Tractors, beginning with the 9N. The picture is from the Robert N. Pripps' book, "How To Restore Your Farm Tractor", c 1992 MBI Publishing, ISBN 0-87938-593-6, and shows the oil filter housings for the N's. Bob Pripps followed the late Palmer Fossum around when he was restoring his *9N357*. He states the rounded bottom one is correct for the early 9N and the "scallopped" one is for the later N's. The question is when was the rounded bottom style obsoleted. The March 15, 1940 Master Parts Price List Book states the oil filter housing as part number 9N-18658. The part number is also the same in the '41 and '42 MPB's. The January, 1946 MPB shows the part number changed to 9N-18660 and covered 39-45. The July 1947 MPB also lists the housing as part number 9N-18660 '39-'48. I don't have access to any MPBs from '43; '44, or '45. This would be interesting to see how many rounded bottoms are out there and if we can nail down the date this change was made.
