Reinforcement plates [That was added before June 1930] ?? If you did not have the plates then you would have a 1930 early Standard cowl for a roadster/phaeton. If i was starting out i'll go for a "LATE" 1930 [Nov. Dec.] .2 piece running boards , easy to fine a nice 1930 radiator shell then a 31, easy to fine or buy front fenders w/o the horn piece because of the 2 piece running boards OR fine a really nice 1931 radiator shell and have a early 31. 31 radiator shells are getting harder to find. Bob are you going to the A.A.C.A.Nat's upstate N.Y. on June 4.?
