Well, I can tell you this much. Your tractor is a 1966. The 6020E is a 6hp model that should be equipped with electric start, and the deck model # indicates its a 32" deck. I believe this is the model that came with no fenders and only the half drive belt guard, but a picture of it could confirm that. Interestingly enough, the model and type #'s off of your engine do not exactly correspond with either the Moto-Mower or Lawnmaster version of this tractor as listed in the 1966 service manual, indicating that there were probably several different versions of this tractor available. So now to the tricky part...where to get manuals and parts. All of the Moto Mower stuff I own with the exception of the one tractor and its attachments came through ebay. I've got some stuff pretty reasonably, and other stuff that I really wanted I got outbid. Parts for the engine should be easy to comeby either online, or at hardware stores or dealers that deal with B & S stuff. Many other parts on the tractor are obsolete and can be difficult to track down. As to what its worth, without seeing a picture its hard to place a value on it, but if it is in good shape its probably worth a couple hundred dollars anyway.
