Plenty of shots of De Wolfe catalogues here:

Hey thanks for those links. Man that catalogue sure could have made my life easier haha. A lot of the newer cues I found were actually listed in that "Space" section, so that would have helped a lot!
Also thanks for those banjo cues. Unfortunately I've heard them all (they're all on DeWolfes site) except that one from Dinky Doo, which would be a surprise if it turned out to be that one. Interestingly on DeWolfe's site, they have Shep-a-go-go and there's another banjo cue (Coffee and Beans I think?) that isn't listed in there catalogue as a banjo piece.
