Schrade Yeller Handles - Do I have one of each known model?

[Wtrfwl]

Mine is stamped 896Y on the opposite side of the SCHRADE WALDEN markings. Acquired it from an estate sale and when I saw there hadn't been any on eBay in awhile. It's in fair shape. I'll post some pics of it. I'm at work tonight so....

Got home. Here are the pics. Any info on this knife would be greatly appreciated. I can't find anything about this knife.
