Enjoy your trip to the mountains, Felix (@fxrob). I hope you have a great vacation and new year.

I found that window in walls in nose has a very various types with their bulged shape. Producers of aftermarket decals not always recongised differences.

I found three different shades excluded flat window.

1. Strange bulged, 2. ridiculos rectangular bulged with various extra bulged windows (I have very nice decals for it but How can I made extra bulged windows?), 3. standard Airfix Bulged. 4. Flat.

Airfix kit has only option four or has various extra parts?

Indeed, too many variations on those windows, my friend @lis! Looks like you must gave photo evidence of the specific bird you are building, if you want to be accurate.

@fiveten Hard to find good version. I'll see if I can find the perfect version or turn a blind eye to it.
@fxrob I hope in next version will be more options.

@fxrob. Valiant Lady has bulged window type B. So Airfix don't recognize options. what's worse, aftermarket decal manufacturers don't understand the topic at all. What a disappointment it was to find out that Naughty Nan had these weird no. 1 windows.
I found Type 5. Sth between 2, and 4.
Type. 6 - egg

On Areomaster Decals there is no differences in waist nose windows, but in Bombardiers window- yes (for H version more triangular shape).
PS. What would You choose from this paintings? Did You ever make research what Numbers of bomb groups take part in operation Market- Garden?

Decals do look great, Bernard @lis
Add me in for Foil Proof as well.

B-24s are many times obscure subjects regarding decal accuracy, my friend @lis. It is very probable that Foil Proof's decoration evolved with time.
