Okay, that makes more sense! Generally simple saddle-blanks are carved to custom specifications or pre-shaped saddles re-carved with simple changes made and so there isn't a big selection available because carving a saddle from a simple blank is no big thing. (There have been several posts in this forum on doing it.) There are a few places where you can buy pre-shaped bone saddles (or blanks) like
Stewmac.com or
Elderly Instruments. Either of those can also supply pick-guards or pickguard material blanks.
Anyway, I hope that helps and welcome to GTU.
