I have contacted the owner re these carbs this morning. Due to info Tony needed I found this additional info;
1) carbs butterfly shafts are tight, no play.
2) on the butterfly itself it is stamped - 79 degrees 30 seconds.
I need to find out how to have the "reply" from other AlfaBB members go directly to my email.......

By the way "skip"...........regular Weber's are nearly $2K a set..........these are nearly consecutively numbered set of Italian sand cast. Apparently back in the day, they produced a group of carbs at a time, so these are keepers. These are very rare, nearly unobtanium......for 100% correctness these are irreplaceable!! I know...I know...lots of money though....wish I was getting the dough myself!!
