I have been researching the four Boeing 307's that were bailed back to TWA in 1944 as C-75's. According to written sources I found, they were fitted with wings, engines, and stabilizers from the B-17G. In photos I have found, you can see the B-17G horizontal stabilizers, paddle blade props, engines, cowlings, and wings with the slots for exhausting air from the intercoolers that were fitted to the G's. My question is: since the wings and powerplants from the B-17G were fitted, did these four 307's also have the turbosuperchargers? I have found no photos of the underside of the aircraft so modified that shows whether or not they were present. I have my doubts that they were, as there don't seem to be any intakes in the leading edge of the wings for the intercoolers or oil coolers in any of the photos I have seen, and the exhaust does not seem to be that of the B-17G, It would be nice to know, as I wouldn't have to fill the space normally occupied by the superchargers on my donor B-17G kit, but I wanted to ask the assembled experts. What do you think?
