This one's from the 6th NFS's Detachment A, based at 12 Mile Drome, near Port Moresby, New Guinea in the summer of 1943.
This the the camo scheme I mentioned earlier, the one the Brisbane depot put on the first batch of P-70A conversions, the ones fully designated as P-70A-1. Only the cowlings and the neutral gray undersurfaces were sprayed in flat black, with the rest of the plane left in the original olive drab. The skin is an authentic camo scheme applied to the twelve (one source says thirteen) planes of that first Brisbane batch, but my assigning it to Det A of the 6th NFS is presumptive, as I could find no photos of these planes at either of the operational locations, so who knows if any A-1's actually went to a combat unit. If they did it had to be one of the 6th's detachments because at that time there weren't any other night fighter units in the Pacific.
The P-70A-1's were conversions of conversions. They were built as glass nosed A-20 bombers. Early in the war "Pappy" Gunn and his folks got to work on the 3rd Bomb Group's A-20's and turned them into strafers, with four more forward firing .50's in the painted-over nose above the two that were already there. Then, when they were traded in for B-25s, the Brisbane depot added radar, sprayed the cowlings and undersurfaces black, and they became P-70A's. Later Brisbane and stateside conversions were made from early A-20G's from before the Martin turret was introduced, and then the two sub-variants became A-1 and A-2.
So here's a P-70A-1 in the unique camouflage of that sub-variant. Whether it ever really joined the 6th NFS is, to the best of my knowledge, a matter of speculation.
Steve, this one uses your 3rd Bomb Group A-20 for the base textures. I just sprayed black paint where the Brisbane depot did and gave it a serial number. I put those mid-1943 insignia on it because I like that stye of insignia, and the plane was around at that time.
