Strictly A's in SW Missouri offers this OEM original Gas Tank Flame Arrestor used in early 1928 and again in the later 1930-1931 Model A and AA vehicles.  This was cleaned and cadmium plated as original.  It is solid and unfortunately most rusted out on the bottom but this one is in great shape and would be correct for a fine point car or truck in judging for both MARC or MAFCA national or regional meets.
