AVO 8 Mk. II. 1963 vintage. Shown in oblique light for a little bit of relief. I had to fit a new glass to this otherwise perfectly working instrument, and it can be seen that at some point since 1990 (I would say) it has been fitted with shrouded terminals. The fascia was grubby as well (pics to follow, but are on a film-camera and might be some time!) so I cleaned it with a stiff brush, elbow grease and a little 3-in-1 oil.
