In reply to Dom Bush:
Jim Birkett 's wife left him in 1944, so he got back into climbing that year (Jim never climbed when he was married). He started with the girdle traverse of Esk Buttress, (VS) and followed this with Serpent route, Frustration, Afterthought, Chimney buttress and Reunion climb (not recorded in the guide). Over on Blind tarn crag he added Cinderella.
Over on Overbeck buttress, a young John Wilkinson added Zig-Zag, not bad for a kid who's still in the FRCC club.
The only other significant activity in the Lakes was from Bentley Beetham, who added a dozen routes to Borrowdale, mainly around Combe gill.
Cheers
