Well, yeah, OEM 9N & 2N's were painted all Ford Dark Grey, M2888. The Vermillion wasn't released until the July 1947 8N Model, as was the Ford Medium Grey scheme. Your tractor, your call. TISCO paint is made by Van Sickle paint Co and closely matches anything out there. The 8N Red is matched by the TP-110 IH RED though, all other Ford marked labels are too orangey. CNH does not make the IRON GARD brand in the M2888 shade anymore.
FORD TRACTOR TISCO PAINT SHADES:
9N/2N = TISCO M2888
8N = FORD VERMILLION (RED)M-2822 - TISCO IH TP110 CLOSEST MATCH
8N (AND UP) = FORD MEDIUM GREY TISCO TP-13243
8N (AND UP) = *CNH IRON-GARD© ®™ M1J-957 SE4DS
*NOTE: CNH brand says used '39/62' but that isn't right. This is the FORD MEDIUM GREY and not used on the 39-47 Models. CNH no longer makes a Ford M2888 Dark Grey shade.
