Further info as to the confusion. I thought 900528 was quite odd for BuNo because current ones always start with 1. I guess it orginally was 90-0528 but since it went to the Navy they dropped the dash to make it conform to their style. This is not without precedent; I have seen Army/AF numbers in the past being converted to Navy format, but the numbers were such that they fit - no examples off the top of my head. I've also seen the reverse when the AF takes a Navy bird, and a good example of that is the A-1 Skyraider at the Air Force Museum. It's BuNo. is 132649, but the Air Force added a FY number at the front to become 52-132649.
Speaking of that Skyraider, the links added an extra profile under 132649 because fthe profile for 52-132649 uses the BuNo for the c/n. If you were to correct the c/n on that one to match the one on 132649 - i.e., 9506 - then you would be able to get rid of that extra profile. You could also put the year built - 1952 - on the 132649 profile.
