Hard to tell what year, 71, 72 or even a 73. It has a blacked out grill though the grills are supposed to be silver on a Formula. I think I can faintly see wide grill blocks that would be 73 grills. The 72 grills have a definite honeycomb with no horizontal bars. The 71 grills have a fine square block pattern.
1971:
1972:
and 1973:
Also I notice it does not have a nose emblem on top of the beak which only the 70s' and 71 Formulas had. 72s and 73s did not have the emblem.
