Saw these a long time ago in the SDASM archives and forgot about them. Photos state "VMB-612 Experimental Squadron 1943". Taigh Ramey perhaps is still looking for some stenciling detail for his PV-2 rockets. There's some good detail in a few of these photos.
There's some other nice stuff I shall post as well.

Neat looking setup here. Pretty powerful tractor by the looks of it.

I can read the stenciling much more clearly on the photo before I post on WIX

Any idea what that device is used for?

Another question mark on the plugs I see in a couple of shots.

Solid navy blue for the whole airplane? Assuming the same as the CAF's devil dog?

Assuming an experiment here.

Interesting how small the star and bar are here.
And a few interesting items ...

PV-2's off the Aleutians with P-38 escorts

P-51C with double wing tank configuration, notice the wood braces. I believe this was taken in the CBI theater

P-51C with an assortment of "stuff", notice again the wood braces. This must have been some sort of mock up?
