@LONANRANGER If memory serves the 634s was available with a crotch rivet by request only many moons ago, c.2008 or '09, or maybe a little earlier. Back when you could get silver rivets, too. Wish I would've gone for the silver…
@sabergirl - Thanks for the response - picked up a pair of as new unworn IH634S with a crotch rivet and wonder when they were made
