I got some numbers. I got a hit from a British obsolete auto parts site but the page is no longer there. It was for the starter number. Here's what I found.
1. Starter: Stamped in case 161-4237 Patent dates 1916-1917
2. Generator: Stampen on case 1333567 patent dates 1912-1916
3. Distributer: Stamped in case D1 80 800 ID plate says DELCO Starting Lighting & Ignition System patent dates 1914-1918
4. Exhaust manifold cast A-50047 with a square G under it.
5. Cast into side of transmission F59-1
6. Cast on top left of crankcase/bell housing BH BF4-4 19 ( maybe a casting date like April 4, 1919) Under that a large B
7. Cast on top between back of block and bell housing 4 80009
8. Stamped on raised oval boss on left front mount leg of main casting 14 955
There is nothing on the carb. There was a top plate held with 4 screws that is missing and probably had all the info on it.
