Its supposed to be 50 years in the past 1930 and a Philips 930A plays a couple of significant roles but of course the 930A is 1931/32 however as it's such a nice set I forgive the props department
It first appears in its full glory at 07:57 ish
Later on David McCallum pops a couple of bottles and sticks his fingers in the sockets to open a door
Worth watch just for the lovely Joanna Lumley.
Cheers
