Hi guys....

So as to dots the i's and cross the t's, I've reproduced the response
from Rega concerning the mystery turntable:

From the link you provided that is certainly one of ours. That is the
original REGA PLANET ACOS TURNTABLE, it must be 25 to
30 years old. We used to purchase the ACOS arms to fit to our
turntable before we manufactured the now famous RB range of
arms.

Thanks again to all who supplied a positive response to my original
enquiry...

cheers

Pete
