Big Twin Guzzi Quasar

I snapped this photo in Malcolm Newell's workshop circa 1986. We think it might actually be the Guzzi Convert Phasar in a new guise, but we're not sure. We know that Malcolm "robbed" the Tait hub centre steering off the Convert for another project, but we're not certain that it was then turned into this Twin Head Steer big twin Quasar-Guzzi. Nor do we have any idea where it is in 2008......PNB.
