Thanks for the reply, it was nearly 40 years ago but here goes;
One piece
Not sure on needles or LEDs
Single aerial
Single deck
No idea on brand but top end
Mid to large size
Knobs, not sliders
I'm thinking maybe Sanyo,JVC, Panasonic, Crown, if I remember the woofers were silver.
It's like looking for a needle in a haystack, but appreciate your input very much.
P.S. The cassette keys were serated or knurled at the base and servo'd, hope this helps.
P.P.S. That Aiwa looks close

but chrome bezels.
