In my book, it is London to a brick it was an SME Model 30 turntable, except for the date! The Model 30 was released in 1991, not 1981.
The Model 30 was SME's first commercially released turntable, and it cost megabucks (well 9,000 quid in 1991!). Weighing more than 42-kgs the table featured a suspended sub chassis, hanging from four pylons like a big-top circus tent. The pylons each had 15 rubber rings and were also fluid damped.
