They are a very solid mower with alloy deck, only downside is the bar blade
I suggest the correct age of the deck is before 1978 as after that they had usually had poly catchers (very heavy ones at that)
Another model name was the Jaguar - although they may have not come with side discharge chute (only rear discharge)
