I have in my possession a group photo of what is simply called 17th Air Base Squadron. It does not mention HQ or HQ Squadron nor a Material Squadron.
The photo is dated November 1941.
The odd thing is that the writing at the bottom identifies the squadron on Wheeler Field rather than Hickam. All sources I have found show Hickam to be the correct location. That is the only reason I started searching about it and ran across your post.
Just trying to figure out about this group of men.
