I remember paying $20 for my first NOS fishtail from White's HD in Lebanon PA, probably around 2002. Got it through Hannums in Media. By just giving the part person a list of stuff to check dealer stock to see if they had anything I wanted.
Then got another pair of NOS that I used on my '65 restoration for $400 a year later at the Chesapeake meet.
All 3 of mine were extra quiet versions (-62A)
Prices on these have increasingly gone to insane. But you don't really see too many new ones any more. Figure the judges can still look for the numbers so it's one part that needs to be right or just live with a point bump on a restoration.
But this one seems insane to me. Someone really needed it.
Getting harder and harder, else it's just an Ebay thing.
It will be interesting to see what the next NOS -62A goes for.
