there is none. this is what the "PT factory" seems to be shipping as the 93150 now
DISGUST!
official response "they dont make that style anymore" more or less a waste of money. maybe jmb could re-engrave some 93150 on those ends ?? and the use of the shorter screws that dont fit all the way through the link due to the crappy metal used causing them to break off in the hole. solution shorten the screws = less tension. HAH. re engrave the end, pair it with a gen clasp and bracelet links from a proper bracelet. but if youre doing all that why buy it in the first place? theres nothing left but shatty metal, 580 endlinks and the endlink bracelet connector..which is also incorrect.
