I'll see if I can find some of the crews. Col. Haynes flew 25 missions in Thumper (according to one article). Haynes was an airline pilot and Lockheed test pilot before the war. He joined the RCAF where he flew Wellingtons then on to the 8th AF flying B-17s, (some 78 European missions according to one article). Haynes then went to the 497th were he flew "50" missions in the Pacific. Thumper arrived in the Pacific on October 18, 1944 and returned to the US in early June 1945. The bond tour may have started in July, as one article mentions the crew got a 30 days leave when they returned to the US.
It is interesting to read the various newspaper articles about the tour, as there are different bits of information (hopefully facts) in each one. One article says that the crew flying the plane was the first complete B-29 crew to return to the US after having flown 30 or more missions. At other stops on the tour there is often some local connection. One stop talks about one of the ground crew (a local boy) who was an engine mechanic for the plane while it was based at Saipan.
As an example of how the "facts" get confused, some articles put Haynes' missions as 75 in Europe and 33 in the Pacific. Haynes himself made a distinction between bombing missions and other missions he flew (such as lifeguard or weather missions), so that might be part of the confusion. Another article says he flew 108 combat missions, which could be 75 + 33.
Another "fact" in one write-up says that Thumper was the first B-29 to fly over Tokyo. I believe the first B-29 over Tokyo was a recon ship "Tokyo Rose" on November 1, 1944. It was flown by Ralph D. Steakley. (The plane was named after the flight.)

The photos were so good that some were used until the end of the war.
Thumper was one of the planes on the first bombing raid over Tokyo, November 24, 1944.
Update 1: Found another pilot. Captain Charles C Fishburne, Jr. of Darien GA. The line in the newspaper that mentions this says he was the pilot for a "majority" of Thumper's missions. Now if Haynes flew 25 in Thumper and the plane flew a total of 40 then this "fact" does not quite fit. (Part of the confusion may be how the Thumper missions were counted, 40 actual bombing missions vs total missions flown (which may have been 50 or so). )
An interesting odd fact about Fishburne is that he was the first pilot to bomb Tokyo in the new year of 1945, according to several newspaper accounts in January, 1945.
Update 2: Found another pilot J. M Campbell. There is an account of one his crew here:

Searching for A-21 in the above shows 9 missions (two of them were weather missions, not bombing missions).
