Very rare single carb version of the Star Twin, also features later Unit type Fork Sliders and compression ignition which does not require HT leads to be connected..... Not what is seems, in my opinion.
Swarfy.
Additional.... A view of all pictures on FB features a view from the front. A non symmetrical cowl over the headlamp rim is a classic indication of a twisted fork setting.....or an attempt to steer straight with a bent stanchion. Yup, been there, done that!.
