At first sight you'll probably think I've posted this thread on the wrong board but I think you may be more knowledgeable about telephone numbers than those on the other board.
I'm trying to come up with a more accurate date (year) when my Decca Leggero cassette recorder was made, instead of my 1968-72 guestimate.
It still has it's original guarantee card, on which the following address and phone number is shown;
Decca Radio & Televison, 15-17 Ingate Place, Queenstown Road, London SW8. Telephone: MACaulay 6677.
I've searched the t'internet for more info and found a list of London telephone number changes (as of 1968) from letter/number configuration to all number ones and MACaulay was shown as 622 (Nine Elms) but it didn't give when (date/year) this change took place.
Here's the info I found:

Can anyone help me home-in on the year more accurately?
Cheers,
Tony
