I just purchased a Wheeler and Wilson treadle machine last night and will pick it up on Wednesday. So now, the research begins. This machine is probably late 1800s but does anyone know where I can start to search for information about how it works or what it needs if it needs something? It does have the belt, a short length and wide, probably 1".

Thanks for steering me in the right direction. I'll post a picture once I get it home.
