early dodge parts?

[harvest]

i recently got my hands on some old car parts at a garage sale and was wondering if they could perhaps be early dodge. The oldest dodge I had owned was a 49 many years ago and this stuff is older. I was wondering what the members here might think they could be.  the 1st pic is I believe for the underside of old seat?  the 2nd pic is made of solid brass and could it be part of a wooden cab?  the 3rd and 4th pic is a pinion and gear that I think is for late teens/early 20s dodge.  the box says speed set Romar.     thank you

Count the teeth and divide the little into the big numbers and you will know the ratio.

Romar is a Dodge Brothers reproduction parts place.

What are the numbers and letters stamped into each part? We might be able to get a cross match from them.

 

I could not find a match in a quick scan of the Republic 1944 catalogue thus they are post war? The catalogue lists parts for DB cars from 1922 to 1942.

Bingo! 1922-3-4-5-6-7 4 cyl. aft. car 715469, 49-14, spiral bevel "speed set". Ring gear bore 6.75", OD 11", 12 bolts 3/8" - 24.

 

"Speed sets" after this date were 49-13.

 

Chrysler and GM brands went hypoid in 1937. Ford went after the war, as did Hudson-Terraplane. Hupp. had Hypoid diff's in their 8 cyl. 427 1932-34 (others still spiral). Trucks still spiral until after the war. Lincoln-Zephyr hypoid from 1938. Nash hypoid 1941. Etc...
