Many studios had both and so could have produced
bin loop masters in either format.. Maybe it was the
player manufacturers who chose Dolby B?

IIRC, Philips only licensed the use of their format if their specification
was adhered to. Anything else would be a nonsense.

Agreed. So was it they who specified Dolby B ?
It was the right choice!

Dobly B was not a part of the spec.

The C cassette was launched in 1963 and
Dolby B was first demonstrated five years later

The Compact Cassette was introduced as a mono format for dictation
machines, etc. Philips were sensible enough to allow it to be used under
license but free of charge. But did retain a degree of control over the
basics.

I'm not sure if this included the use of Dolby B or not. But did over the
basics like speed.

IIRC They mandated aspects like the physical dimensions (inc. things like
track widths and spacings), but I'm not sure about which 'electronic'
details they might have defined or limited.

They did try to flog their own 'noise reduction' (DNS?) system which was
single-ended. But I don't recall that they could (or attempted to) block or
control the adoption of Dolby. If nothing else, they couldn't have stopped
anyone from buying a Bolby adaptor box, anyway! Given how good Dolby was
they probably twigged quite quickly it would be good for sales, and hence
their own deck/cassette royalties!

The spec laid down in Sept 1963 could not have included Dolby B
as this was still five years away from the first demonstration in 1968

Yes - you made that point earlier.

Did you miss the bit about the original purpose of the compact cassette?
