I have found a old Champion Mowing Machine that belonged to my Wifes father. It is + - 70 years old and has sets of numbers on it and the name of Champion and BF Avery&Sons. The #s are AA1165 and AC1221 and AB1188. I would like to restore it if possible but i don't know the bast place to get the parts of at all possible. Can anyone help me ?
