early Carb ID - Detroit, Stewart, Tillotson?

[Pontiac59]

I picked up some early carbs but no idea what they go to.

One is a Tillotson model JR-A. I found a lot of listings for Tillotsons which gave applications, but none with this model. It's an updraft single barrel with a 5" round air cleaner on it I can post a photo if it helps, but it's a large enough carb for a motor vehicle engine (I know they made a lot of small motor carbs).

One is an International Harvester stamped 15-30, again an updraft type.

One is a Holley model N - believe this is Model T Ford. Has part of a manifold on it.

The last one has these markings on a round piece on the side: "Detroit Lubricator Company, Detroit USA", patent dates in 1911 and 1913, and "Stewart J2B5" - all in raised, cast letters. Below the J2B5 is a pad for some stamped numbers: "6-231" (6 could be an 8). Here again I could post photos, but this is another updraft type carb.

I searched eBay on the last one and found a listing for a similar carb that indicated it was for an early Dodge Brothers car.

Anyone have any ideas on application or where to look them up? The only carb references I have are Motors Manuals (back to '35 only) and a big Carter book.

Thanks -

I figured the Holley would be easy, but I guess not here.

The Tillotson is a JR2A, the 2 was stamped pretty faint on the pad.

Still not in any online lists - no one has any old carb books around?

Model T Fords used Holley G and NH.

Pictures would be the best thing to do.

This carb on eBay is virtually identical to the Detroit Lubricator I have here. I have tracked down the cast J2B5 may indicate 1926 Dodge. This seller has not included the numbers and they do not show well in the photos.

The carburetor in the link above is for an early Dodge Bros. 1915 up to about 1918.
