Wikipedia:WikiProject U.S. Roads/Oklahoma/Farm-to-Market Roads
State maps from 1932 to 1953 show some Farm-to-Market Roads with "FM" in a circle (later a diamond). On the 1954 map they are given normal state highway numbers. One of the photos on [http://www.okladot.state.ok.us/memorial/route66/route66f.htm] is labeled "Signing at US66 and FM4", but this portion of SH-4 was never a Farm-to-Market Road on the official map.
