Hi, I recently acquired this, what appears to be a WW2 Dennison, 2nd Pattern that may be altered with button Loops in the collar. Or, from viewing previous threads, it may be a Royal Marine alteration design.
My interest is the "painted/screened/drawn" Jump Wings on the right breast. Has anyone ever seen this, or have any information, origins, ideas for this drawing.
Any comments, thoughts, and/or ideas about this smock would be greatly appreciated. Thanks.
