  The front panel is light-grey Bakelite, the rear of the case is metal in earlier examples and grey plastic in later production. It is also possible (but not certain) that the design of the meter movement may have been changed some time after 1966. There are two typographical errors in the AVO Working Instructions on the parts list:- - It is titled "Mulitminor" and - switch position 12 should read 100 V a.c. (not 100 V d.c.)
