Curtiss-Electric propellers are extremely hard to come by for the P-47. Even with "Dottie Mae", in which no expense was spared to make it exactly right, for years they couldn't find any available at all (at least not for airworthy use) - finally, last year, UK warbird collector David Arnold provided them a set of original Curtiss-Electric blades, which will eventually be installed on "Dottie Mae" and it will be that much closer to the 100% accuracy factor (to exactly how it was in 1945). Even though the restoration is completed and the aircraft has been flying, they still plan on possibly going back and adding in all of the combat damage repairs/patches it had up until its last mission as well.
I believe the only P-47 that has operated with the Curtiss-Electric prop in modern years is the late Bob Pond/Palms Springs Air Museum example (which unfortunately hasn't been flown since about 2005 - due to Bob Pond's death, and the aircraft still being owned by the Pond family, rather than the museum).
