Hello, Great forum, I was given a 26" Troy Bilt snowblower and was wondering if there was anyway of finding out the model year and where it was sold originally? The engine is a 10 horse Tecumseh Snow King. The tag on the back of the unit reads-model number 42012- serial number 420120201819. It was my late uncles and my aunt didn't remember where it was purchased.Thanks for any help,Mike
