Looks like you have a great starting point for a true classic.
It will be interesting to see what's underneath that bolt on fascia board dashboard someone installed in the past. I am wondering if what it there can be removed, repaired, refinished, and put back in service. I see the throttle and gear lever is new, and the steering wheel. The hardware all looks like it can be restored or replaced in good order. The clamshell vents are potmetal so if you have any pitting they'll have to be flame soldered in order to refinish those, as it's pretty rare to find those on the market these days in good shape put I guess it can be done. The question is, "how does it run"? If the motor is installed and runs well, I would be pretty hard pressed to pull it and replace it until it needs serious work, but for the purist I would certainly understand.
I would lose the swim platform, as I think it detracts from the lines of the boat. Many people will argue this point but it's a preference I have and if I were judging a show I would absolutely mark off for that, especially on a premium collectible like this one. There are some nice stowable stainless steel ladders that can be hidden under the seats for water skiing, I have one on my skiff that is placed in a spot intended for it, and I don't ever have to look at it unless I or someone else is going to get in the water
With a swim platform, you haul it around everytime you are in the boat. Like I said, it's a preference and an opinion, and everyone has one !!
