Those Ivory scales are still being sold, even on eBay. Since eBay does not allow the selling of ivory items, and most of the folks selling things they found at yard sales, estate sales and so on really don't know for sure that they were Ivory. A lot of Celluloid (light yellow) Schales (handles) out there but the really pale stuff with single pins deserve a second look if the rest of the blade is respectable.
