Welcome to BladeForums!
As you may know, Schrade went bankrupt on their 100th anniversary in 2004 and within minutes (figuratively) 'new' Schrade knives were being imported by Taylor Brands LLC; Taylor had purchased the Schrade names at the bankrupcy auction.
Adding to the confusion over Schrade and Taylor products, the market was flooded with anniversary knives from both companies. There were even some sneaky attempts to disguise Taylor-Schrades as originals. And at the same time all sorts of rare collectibles were being sold from the old factory, and employees were assembling knives until the last minute out of anything they could: unfinished knives, mis-matched parts...
My point, in order for anyone to know what sort of knives you have, you're going to have to post a photo. An overall photo of the set and a closeup of an individual knife would be quite helpful.
p.s. Be sure to check out the Schrade Collectors sub-section here at Bladeforums. If those guys don't know about your knife set...
