REPUBLIC Thunderbolt —

UMmmmmmmmmmmmmmmmmmmmm.................
Wasn't the "Razorback" the earlier version?
I see its painted in the Normandy invasion stripping.
And the bubble canopy the later version?
So.........Hun Hunter should be the "G" and not the "D"?

Production P-47B, -C, early -D and -G series aircraft were built with metal-framed "greenhouse" type cockpit canopies. Late -D series (dash 25 and later) aircraft and all -M and -N series production aircraft were given clear "bubble" canopies, which gave the pilot improved rearward vision.

Jim what was the time line on the end of the "Razorback" and start of the "bubble canopies"
Do you know how long it was from build date to when they flew in Europe

Both P-47D models but with different "dash" numbers were built with razorback and bubble canopys. P-47D-20RE's had razorbacks and P-47D-25RE's had the bubble.
Logic would dictate that the 'G"'s came after the "D"'s, but in this case the "G" stood for Curtiss built P-47's.
This info is from my "P-47 in Action" book and this web site,

SNAFU is one of only 2 remaining P-47G's built by Curtiss.
