Finally finished this one, but with different markings than originally planned since I wasn't able to get those decals made. I also noticed after I had painted it that they wouldn't have worked anyways, because the camo scheme on that P-40L appears to be reversed from the standard.   However, I was able to get decals for "Blue Goose II", which is a P-40F from the 85th FS and flown by Lt. John G. Hoagland.  

Little bit of progress.
The aftermarket cockpit placards are easy and really spruce it up!

Looking good!

Painted up the bronze green parts.
Got about all of them except the canopy interiors.
Humbrol 226 is a really nice bronze green.

Thanks Vince.  The seat belts are Eduard's Steel ones, included with its 1/32 Look set for the P-40F.

Interesting; I can see the old photos on my phone but not on my laptop for some reason.

Yes I can see them and they look great!
Awesome job!
May I ask what you used for your seat belts?

Hmm.  All my previous photos here seem to have disappeared  Hopefully these ones of the finally finished model will make it.

Edit:  They appear to have.  P-40F flown by Capt. John R. Anderson of the 85th Fighter Squadron/79th Fighter Group.  Finally got some custom decals made.

This an actual eBay sale for a new build P-40N seat!
The kit uses the same seat and this is a great reference.  So I will weather the edges where paint rubs off as wood and not metal (except the bottom lip)

I haven't seen that before, very interesting. Good questions, I haven't ever heard why they would do that? I don't know how much actual gunnery practice they got back then, it wasn't like it is today though. Maybe this unit was for learning combat maneuvers and tactics?

Before WWII vintage photos on this page are the only ones I have seen, and the one with the gun covers in the black and white, I didn't see until this unit's main page.

It's an easy modification to do, it would be unique from other P-40's, and you have photographic proof of it, so it was at least used on some aircraft. I would go for it 

Here is the photo showing the guns fairings covered with "plugs" which I have rarely if ever seen in photos.
I may model mine this way.
Does this mean the advanced training group didn't do any gunnery training?  Or could some of the birds still have their guns??
I have only found about three photos of this group.
