Sounds like you have a lot planned for your Polysix Strph. I am sure it will look great when you are done.
I forgot to say I agree with Jonathon that Robert Sitek aka mintsite on eBay makes excellent wooden cases. I bought one for my Polysix, made from Iroco wood since it was half price....probably someone ordered it then decided not to purchase, who knows. It has a beautiful orange tinge to the wood, and brings out the Orange of the Arpeggio button, LOL. I figured seeing as I have the Kiwisix upgrade my Polysix wasn't a purists P6 so wasn't worried if it didn't look like the original laminated case, but I would suggest if you do want to keep to a more authentic looking wood, probably Walnut is a good choice. Have a look at his cases for ideas, just search Polysix Case on eBay and you should find several made by Robert. :)
Best of luck with your restoration :)
