Ex 1970's domestic audio equipment, a loungeroom dominating beast called a radiogram!
I think it was an HMV but in those days I did not properly record where I had obtained components, just putting them away unlabelled.
Please look at the photographs and read the description below to try and ascertain if this knob may suit your own equipment.
UNIDENTIFIED MANUFACTURER - MEDIUM KNOB
Silver coloured (looks to be brushed aluminium) outer with an inner Black plastic shaft insert to suit a 16mm fluted shaft
Knob has straight sides (not bevel shaped) with ribbing all around
Small Black indent on the flange which is intended as a 'pointer'
Towards the base of the knob there is a bevel which extends the diameter - see the dimensions below
Dimensions (Digital Calipers):
Knob 15.95mm OD (top) or 19mm OD at the base (flange area) x 19mm height
KNOB DESCRIPTION:
Very small Black pointer at the base flange
Ribbed sides (for easy finger gripping) with a base flange
Aluminium (looks to have been brushed) main body, not metallic paint
16mm fluted shaft socket is Black plastic and is inserted into the underside of the Aluminium knob and fastened with a Brown glue.
CONDITION:
USED
CLEAN
There are some light 'oxidisation type' marks down some of the ribs - metal cleaner did not shift these, however, they are not terribly noticeable in any case.
NO severe scratchings or other markings
Knob face(s) are all without scratches or marks
Fluted shaft is undamaged - no stripping
Since removal, I have now carefully packed and sealed these knobs in individual clear plastic packets to preserve their condition.
