Hi all, thanks again for a fascinating read. I've had a read of Ken Merrick's HP Halifax, from Hell to Victory and Beyond as @Graham Boak suggested, which had some very useful information: images of DT643 with the Tollerton, DT792 described as a 'special' with the mid upper fairing turret, and descriptions of tests carried out on 'specials', including DT744, which is described as having the Tollerton nose, no 'saxophone' exhausts and MKVIII turret with the fairing. This aircraft was shot down on 30th March 1943, a few days before DT635 was lost on an Essen operation. In Halifax At War by Brian Rapier I also found a drawing of Halifax DT579, which has a Tollerton and the raised turret (I can't insert the image here but happy to send to anyone interested). I suppose if the aircraft were constructed in order, DT579 , DT643 and DT792 all having the Tollerton nose would logically suggest that DT635 did too. So it seems I need a Tollerton nose – if anyone has a spare one from the Revell Mk III kit or if @Colin @ Freightdog Models has one down the back of the sofa I am all ears.
cheers all
