A set of gauge for the first generation Nissan Skyline - the C10 a.k.a Hakosuka.
This I believe was fitted to longnose (six-cylinder) non-GT-R sedan & hardtop. Hardtop GT-R does share this gauge but with a 11,000 rpm tachometer.
Been stored for many many years. Untested but looks to be OK. Missing a few bulbs and air inlet /valve. Otherwise pretty much complete. Selling as is.
