This HUD is marked PDU Type 546 and has Serial Number 06 so it was probably manufactured around 1970. This remains one of the smallest HUDs the company has made with a Display Unit containing little more than the CRT projecting through a 3" optic with a 20° TFoV. This one has been modified with an internal battery powered LED and graticule for use as a lecture demonstrator.
