Where were Marvel-Schebler carbs made?

[Jemelton#]

I grew up in Springfield Illinois, and during the 50s and early 60s and I remember that there was a Marvel-Schebler factory/foundry near my Jr High school.


I would walk past this factory on my way to school and now I am wondering if this was where these carburetors were made?


Anyone have an idea if this was the place? or just where the heck they were manufactured.
