I also found some B/W pics of this particular bird and it quiet apeals to me as it's a camouflaged one with a nice tail fin logo and Kokutai? nr.
OO - Good job on this beastie so far. I am in a similar battle with a Combat Models 1/48 scale Mercator (P4M), some of which I've started documenting on our modeling club website (hamptonroadsscalemodelers.com) Labor of love, these are... plus, it flexes the ol' modeling skills and expands one's horizons, I expect.
If you can get one, the Koster Aero 1/48 Nell is a gem to work with (would be a nice break from the Peggy once done!) Also, Bill sells most of his decal sheets separately so it might be possible to pick up a Nell sheet to help with the Peggy.
Looking forward to your progress - and thanks for leading the way!
