I've been doing some checking of files and archived photos and here is what I have found. First a quote from here by UH Fan, the former Schrade historian:
Schrade didn't have a whole lot of info on these knives. I do know that there were approximately 10,000 of the first set manufactured, and they were manufactured in 1978. (Can't find any records from Schrade to back the claim that there were 4 different sets). This set marked the introduction of both, the 144 and the LB7 w/ staglon handles, as well as Schrade's 75th year in business. The following year, the 144UH was added to the regular line of Uncle Henry knives, and in 1982, the LB8, which is the LB7 with Staglon handles, was added to the Uncle Henry line.
From what I can tell, the Dixie Collection was sold to three customers: Parker Frost, Orgill Brothers and Smokey Mountain Knife Works. I have a good pic of the set, but I'm new to this, so I haven't quite figured out how to send it yet.
Digging through my photo archives and saved posts, I find these references to Dixie Collection Editions, some dated, some not:
