I picked this up at a rainy moving sale today I have never seen a ford wrench like this before the markings are ford USA m-01a-17017 D any ideas?
Later than Model A perhaps, with the rev level 'D'
"A" prefix indicates the part was used from 1928-1931.
"17017" identifies this as a spark plug wrench
"B" suffix indicates this was revision B
I think it's for a 9N Ford tractor. The 01a prefix indicates 1940.
I have that same wrench in my model A tolls but didn't know what it was either.
I've had one forever. I have no idea where it came from or what it's for. I always thought it would make a nice handle for a tool box or something.
Ted's right, although it could be for 1940 cars or pickups. B was Ford's prefix for 1932 4 cyl. parts; 18 was the prefix for 1932 V8 parts; 40 was the prefix used for 1933 and 34 V8 models; 48 was the 1935 prefix; 68 was the 1936 prefix; 78 was the 1937 prefix; 81A was the 1938 prefix; 91A was for 1939 parts; O1A was for 1940 Ford parts; 11A was for 1941; The few 1942 models had a 21A prefix; 69A or 6GA were prefixes used for 1946 models; 79A, 7GA, or 7HA were used for 1947 models ; and 89A or 8HA were used in 1948. All these part number prefixes were primarily used for passenger models. Commercial and heavy duty truck had their own prefix.
I need to look at mine to see what prefix it has, been years since I really looked at that wrench. I knew it was newer than my model Ts.
I am curious however. Mine, and most that I have seen at swap meets all seem to be slightly tweaked (not straight?) on one or both ends. Was that how they were new? Did they need for the handle to clear something? They do not all seem to be consistent in their offset.
Drive carefully, and enjoy, W2
