The Broadmoor series was introduced in 1963 with the Broadmoor 6 hp. The 707 was introduced in 1966 in 3 variations. 990373/374/375 One was a basic manual start lawn tractor, one was manual start with deluxe tires, and one was electirc start and deluxe tires.
I am pretty sure the 707 was made just the one year as the 717 was introduced in 1967,
I think you got a pretty decent price if it all runs well and mows well. The hi/lo is a plus and was needed or recommended at least for using the roto tiller and the snow blower.
If you don't have them, you can download the manuals here:
