Ayrhead, welcome to the forums. The presence of a truss fork narrows your Sunshine down to two models, which can be distinguished by tyre/wheelsize. It is either a Balloon Tire Deluxe (26" tyres/wheels) or a Standard Tire De Luxe (28"tyres/wheels).

I can't recall seeing a Sunshine with skip tooth/1" pitch. Some relatively early ones (serial number <010000) have surfaced but had 1/2"pitch.The serial number should be near the top of the seat tube.
