Rick,
The "bulge vs. no bulge on 4891" debate is, to me , akin to the PC10 debate. We just can't be sure........... I did her with the bulge per my interpretation of the photos. The popular shot of 4891 in all the books, a 3/4 left front shot (Pg15 Osprey SE5/5a Aces, P79 No. 56 Sqn RAF/RFC, and most clearly reproduced in SE5/SE5a Squadrons by Albatros Pubs, Photo 56/7) appears to have the bulge however is this aircraft 4891 (Coded "6") or 4863 ("G") with the headrest removed?? The only thing were sure of is........were not sure, as I love to say! I tend to lean towards the info presented by Albatros as Ray does his homework, perhaps he could comment here? I am, given your comments on Dr Merril's conclusions, now totally unsure again!

Other then being as correct in your assumptions and conclusions as anyone the model is coming along beautifully. I still have the Encore Kit and have another WNW in the stash, I think I'll do Tony Rhys David's standard with the latter and possibly a night Fighter version with the Encore.
I'm enjoying your progress here, keep at Her!
Cheers,
Lance
