I just got a Dominion Treadle Sewing Machine in nice old wooden cabinet, and I am trying to find out and kind of info on it that I can.. Please help Thanks

I don't know about the Dominion brand, but do know that treadle sewing machines are generally quite old.

The only thing I could suggest is to watch e-bay to see if anyone ever sells a manual or advertise in an antique magazine column wanting to buy one.
