Hi, Title says it all. Looking for opinions on the best model Snapper walk behind Mower???

Cleaning out the garage and I'm getting rid of things I won't need. I have an old mower carb and metal fuel tank. Very little rust inside. I don't know what it is from. It was something my dad saved for about 30 years. See pics. If you want any more pics, let me know. There are no model numbers...
