Hi Merlin.
Yes, the Il2 figures show 1./JG51 had both E-7 (11) and F-2 (21) in March 1942 (it shows they actually received 6 E-7s in March), and I assumed that it was likely Horn would be flying an E-7 rather than an F-2.
I don't know how accurate the Il2 information is, but it's all I have and it has so much detail it just looks right.
My assumption is very loose, but I figured as he wasn't German and probably wasn't an ace at that time, he probably didn't get to fly the best a/c ......
