imo, you have to distinguish between standards and features. some of the features you mentioned wouldn't suit the character of the shoe and as LSL mentioned his dad had a lot of special demands on his list. anyway. 6k is still a lot of dough.
OK, then the salient question remains thus: gemmed or handwelted
Had my finger on the "buy" button since that was listed.
Was waiting for the seller to come back to me with photos. Was 99% sure it would have been a Papworth / SAB. Looks like it's hand stitched
