I have 2 66's, a 10hp and a 12hp. out of all my collection, they would be the last I'd sell! Your missing a couple guards, no big deal though. I see you still have the original seat and muffler, and those are almost always gone.:fing32:
I don't think that scissor type deck was available, has something been modified to make it fit? I've only seen them on some of the later models.
