In this previous post, I speculated whether Captain Osborne was the unidentified officer in the group of officers posed with the Dictator mortar. Unfortunately the image of Captain Osborne was later in life and it was a bit hard to make a solid call. Recently, Susan, from the Osbornedate State Park sent me a wartime picture of W.F. Osborne. This picture sheds more light on the issue.

Based on this image, it doesn’t appear that Captain Osborne is the unidentified officer in the Dictator picture.
