^The Unionmade website provides thigh measurements of their LVC jeans. Having said that, their measurements of the 1967 505's (size 34x34) is off by an inch as it measures 11' at the thigh. Anyway, 501's generally have more room, especially the archival ones.
I'm breaking in a pair of the said 505's and am awaiting a pair of 519 Bedfords. These are off the radar on this forum it seems, as I haven't been able to get any reports on them... I inherited a pair from my uncle in the late seventies that dated from the early sixties and I'm really hoping that the repros are comparable. Anyway, I'm looking forward to getting them and would be most interested in hearing from anybody who has personal experiences with them.
