Regarding the B-25B/C/D, I'm looking forward to the Vertigo model, and I don't want to be in a position that we're both doing the same variants - especially as there are also so many (hundreds of) differences between the early and late versions - it would be incredibly time-consuming to do all of them.
One of the really cool things I got to do last year, was see the last surviving (true) B-25B in existence, up-close, inside and out, which is in private/restricted storage with Aero Trader. Consisting of just the fuselage and tail, this particular aircraft is only 3 serial numbers difference from the plane that Doolittle flew. Having been in and around a B-25J since the age of 2, it was really interesting to be looking into the rear of this B-25B and not only see the opening for the top turret in the rear fuselage as opposed to the front, but also the built-up opening for the ventral turret. At the same time, I also got to photograph one of the few remaining B-25C's, also in desert storage, and this particular one was used in the Twilight Zone episode that was somewhat based on the "Lady Be Good". Also, having toured Aero Trader's storage yard, it answered the question as to where all of the old J-model upper-engine short-stack exhausts wound up that were thrown-out from the Hayes conversions (when the exhaust ring collectors were added after WWII) - just absolutely hundreds of the things (more than could ever be needed!). When I was out there last year, I got to see the Planes of Fame Air Museum and their airshow, the Yanks Air Museum, the SoCal CAF Wing collection, and a few other warbird-related places, but being invited to tour Aero Trader's private B-25 storage yard was the definite highlight of the entire trip - I never could imagine that all of what they have still exists, unused/unrestored. Visiting Aero Trader, it was also interesting to learn about how, because the original Holly carbs are as rare as hens teeth these days, they've developed a way for a work-around where they are able to fit the original skinny carb intakes, so it has the right WWII-look, but still keep the Bendix-Stromberg carburetors internally.
Great news! Only one question John: more or less when the P39 will be released?
I've stopped trying to predict that, I'm afraid. I work for a school district, and some months back it was really looking like the P-39 might very well be completed by around this time, as I had my summer off and completely free, with my standard three months off until the start of the next school year. However, as things tend to turn out, I ended up working quite a lot in late June, all of July, and into early August with some summer school programs, and so I wasn't able to get as much work in on the Airacobra as I had planned. Still, with every day it progresses. As my old friend Damian Radice would have said, I'm currently at the stage where it seems all I'm doing lately is adding a bunch of "dirt, ketchup and mustard" (weathering) to make everything look lived-in, as the base internal and external textures are getting nearer to completion (holding off showing any further previews until it's completed).
