Probably a PST as I dont remember seeing a Ziroli in white gelcoat- The ones I saw were epoxy resin plain.
PST was a splash of Ziroli.
The dark wood is some Asia wood-Prob mahogany
You need to keep it light-P80 overpowered -Original design was DF and they flew perfect with 12# turbine engines
You need a carry thru spar kit. Wings were built up wood unless you have cores cut.
The plans you have is for the ALL wood kit-Real PIA making the fuse-Scotty
