I have 18 out of 61 with Factory 42 backs.AlexanderAustinBresnahanBurns x 2BushLappMcInnisMarquardMcLeanMurphyOrrPerdueSchang x 2StrunkSweeney x 2The borders seem to be darker on the 25's over the 42's on the ones that I have both of. The Bresnahan is darker where I can see the border, but on the left the border is not there on the 25. Too small of a sample to decide anything.I also added my Lelivelt.
