I see you are standing in front of a 28/29? Mine is a 2/29 final assembly stamped on the side sill plate of the body. It has cups which I believe are original. It also has the forged seat hinge brackets. I looked in JS and saw nothing mentioned about them unless I missed it.
Both of the pics are off the internet (not me in the 1st pic). I'm still working on my '28 and it looks like I'll be looking for the bars since mine has nothing. Might take some looking to find some, I see that they repo the cups.
Looks like February 1929 was the change date then, because my 2-23-29 tank date Tudor has the cups and if I remember correctly the hinge brackets are also forged.
Mine also has the drum taillight and the newly introduced 2 tooth steering with the F cast on the housing.
Well, I didn't find any bars but I did get 2 headlights that have Ford stamped in the top. As I understand it these are early '28.
Edit:
I've been reading more posts and it might look like the script on the bucket is early '29.......can anyone shed some light on this (pun intended).
