Here is my attempt at making the Spit's unique "Sutton seat Harnass"
I used masking tape strips, 2 buckles left over from my mustprang and stained it with watercolours to give some feel to it.
The black dots on the harnass is to simulate the 1/2" diameter holes in the straps where the kingpin with splitpin lock would join the 4 straps.
The sutton harnass was interesting in the sence that it had 2 sets of shoulder straps , one attatched to the rear bulkheads with a cable, I used fish trace cable for this and te other was bolted to the seat backrest.
The first stoped the pilot going to far forward in a prang yet allowed him some movement to lean forward and the second kept his butt firmly in the seat.
The only hassle with photos this up close , it shows the slightest imperfection tha you can not see with eyes allone
