'Waverley' Cameo

Hadn't seen C+J in a few years,but as it was on BBC's iPlayer,I watched it again today..I just noticed when "Alan" (Bill Paterson) decided to try his hand at serious radio journalism after his first "Mr Bunny" encounter,using that BRUTE of a tape recorder(!) the "Waverley" Paddle Steamer (Last seagoing Paddle Steamer in the world,apparently..) was berthed on the opposite side..

If Book was in Intelligence B4 finding God,does that mean He's a Shepherd Spy? (Thank You,Spike..)
