Yepper, there were only 130 P-47M production aircraft almost all of which went to the 56th FG. The fillets and pylons were added to each airframe after delivery to England.
The highly troublesome Pratt & Whitney R-2800-14W/-57 "C-series" engine was the only truly obvious distinguishing feature, visibly, between the P-47M's and the D's. The fillet and the paddle-bladed props were both added to D-models of other various fighter groups. (As an aside, the "C-series" engines and the troubles encountered with them by the 56th almost led to the unit's conversion to P-51's! The Stangs had been delivered and were ready to go after conversion training.)
As stated above, the pylons were also added after delivery as the P-47M was intended to be a high-speed fighter-only variant of the Jug. Contrary to popular belief, the P-47M was NOT developed specifically to counter the Fi 103 (V-1) flying bomb. The idea for the high-speed variant of the P-47 pre-dates the appearance of the Fi 103 and the initial high-speed prototype flew more than a year before the first flying bombs hit England. In any case, the P-47D's in service at the time were more than up to the task of intercepting a V-1.
I admit that the issue of the K-14 gunsight is one that has escaped my attention. But often times pilots of many units would have a different gunsight installed, if they were so inclined, and if it was at all possible. The 56th was probably no different in this regard.
JGUIGNARD states that the ProModeler P-47N is the only 48th kit that basically has the correct engine and prop for the P-47M and I am inclined to agree. Has Hasegawa ever released an "M" variant as one of their "special" releases? I don't recall ever having seen one. It'd be nice if they did!
