Based on the plate, this would appear to be a Murray snowblower or perhaps even made by Noma Outdoor products. The engine is a Tecumseh 10HP Snow King engine.
I don't know if either of them is still around, and the engine manufacturer (Tecumseh)doesn't make it any more.
Parts might be a challenge. What parts are you looking for exactly?
