I worked on one similar years ago, AS was imported from Cali USA, dead beasts and old shed snakeskin behind objects we stripped out, damaged panels replaced and solid rivet back in place. The end product was decked with a bar with seating area within, leased out for corporate events, such as Royal Bank Of Scotland attending the Highland Show.
Eventually, the AS was sold on, I wonder if still in use, as they are bomb proof, certainly this one was when completed.
