Alan, the blowup of Hughes where we may or may not see evidence of PM was posted on the bottom of P137 of the Oswald...TSBD thread(and if I sent you to the wrong page last time please except my sincere apologies, I may have earmarked the wrong one and just realised it, this time I doublechecked...).
Also, what you just mentioned about Frazier's jacket, I remember him saying to Gary that he had on probably work boots and denim jeans and yes he did mention his " young farmers logo" jacket but was he sure about that part? Anyway, I agree it's not very likely, it should be very noticable in Darnell.
Thanks for all these images it's appreciated and that little Darnell/Weigman overlay suggests to me that Lovelady was further east than Reese, so I still think he's leaning onto/over the rail in Altgens. I have not the slightest compulsion to put him where the shadow was.
