Hi, I have a selection of RF tops available that come with hollow stalks. The stalks are cast with a carbon tube inside, allowing wires to run between helmet and RF top.
They also have a threaded countersunk hole at the pivot end and three threaded holes at the RF top end (as in the pictures) allowing easy assembly of parts, all hardware included. The RF tops have a cast housing section and a hand cut Perspex lens block held together with rare earth magnets, included is a clean cast of the Polaroid part. Available in PP2, ROTJ and ESB. Price for the kit is £55.00 (GBP) shipped to your door!
