Good to know you had a relaxing Christmas Gerry - by 21.00 hrs last night, I was as relaxed as a newt!
From what I remember from looking at the radios in situ, the cables were behind the two sets, virtually hidden behind the half bulkhead between radio and Nav stations,and beneath the table, with the antenna and remote cables on the port wall and roof.
These two pics, taken in PA474 (BBMF Lanc) and NX611 (East Kirby Lanc 'Jane), although not brilliant, show what they looked like. The chap at the radio is the late Ernie Evison, radio op on CF-O, 'Oozlum Bird', of 625 Squadron.
