Tread design for Bong's P-38 Marge?

[Northwest48]

Anybody know for sure whether Richard Bong's P-38J-15 42-103993 in Cape Glouster, 1944, would have had either diamond or block tread? I can't find a clear picture that verifies either one. The one below looks to me like it could be either one.

Looking for you... his other aircraft with 27 victories (April '44) has the diamond tread.....

Maybe these pics can help.The first pic seems to be taken earlier than the second one which was taken in April 1944

The next to last photo shows something that is of interest to me. The port auxiliary fuel tank has quite a dent in it. I'll try to simulate that. Most models of Bong's P-38 I have seen are done as restored "warbirds". I'll try to make mine as the plane was in 1944.

Glad I helped.
