May I point out that
Fender produce two
Custom Shop 56 NOS Stratocasters
One has 21 frets / normal vintage tuners / boat shape neck / vintage 50's Pick up's,the pick up's cannot be bought from fender, they are made only for that guitar, and you find the strings go over the magnets spot on.
The other model has 22 frets / locking sperzels / C shape neck (satin finish) / vintage noisless pick up's, these pick up's can be bought from fender, it seems on this model that the first string is slightly to one side of the magnet.
Both guitars come with Birds Eye maple neck/ Gold Hard Ware / Fiesta Red......
So when looking at these guitars just count the frets and it will help knowing what model your viewing ...
Hope this is some help.....
Non Shads Models ! (Fender make the 56 nos chrome h/ware/ standard maple neck / relic/ closet )
