Summary continued: No, the wooden gas tank cover hinges for the wooden seat frames used on “some” but not all 1915 and later 1918-1919 T’s are NOT the same as the ones shown in Keith’s photos.

From the on-line Model T Ford encyclopedia that Bruce created at:

1915-1922
FRONT SEAT LIDS T-7266
(Over the fuel tank)
Two different lids covered the fuel tank in the runabout and touring bodies; one of wood and the other of steel. The wood covers were used on bodies manufactured by Wilson, and Kahler. These were used on the touring bodies only. The metal covers were used on bodies made by Beaudett, Fisher, Kelsey, and Ford, and was used on touring and runabouts.
Dimensions were 35-7/8 x 16-1/2” (The wood lid was 3/8” thick.) The hole for the gas cap was 4” diameter, located (center) 6-3/8” from the front of the lid. The wood board was made of slats nailed together with two 1-1/4 x 34” strips, 1-1/4 from the front edge and 1-3/4” from the rear, centered between the ends of the boards. Twenty-two #15 x 1” box nails were used to attach the strips. There were two one-inch holes located 3-1/2” from the rear edge and 9-1/2” either side of the center line of the cover. A third hole, 1-1/4” diameter was located 1/8’ from the front edge on the center line of the cover. (From blueprints of this assembly.)
Note “Fossil Evidence” i.e. old Fords – appear to contradict some of the above. I.e. Beaudett touring bodies manufactured early 1915 to [from memory – not as good as notes – but I don’t have time to look it up tonight] at least early 1916 used front wood seat frames with wooden covers. Dec 1917 (1918 model year) Fisher bodies – also had wooden front seat frames and wooden covers (ref Donor in loft of Hap’s garage).
