Id also like to know when they stopped using the wood mirror cell and changed to the Hall aluminium one (I think al their DK 12.5" were wood?) . I assume the trap door in the OTA went at the time they changed to the alloy cell if that rings a bell with anyone.

I got their "compact" (FL 1000 mm) 6" Newtonian in late 1974. Which had a metallic blue finish. It had a wooden main mirror cell (yuk!). This was spray painted black with some transparent pvc air hose stuck around the base inside the tube to keep the dust out. In the late 80's I replaced it with their cast model, which was a very nice piece. If I remember correctly the cast model was just coming in at the time.
