I used to have pretty much the same Silver Knight collection, all I have left are the small ducks, the small green checkered scale with the shield, a large black lip pearl a tiny non locking all stainless model, and I think I have a small all stainless lockback, these genes are on my top 10 list of production knives.
Do you know if they made the checkered (I think they're g10) scaled knife in the larger frame? If you've never carried one of these you owe it to yourself to try a Silver Knight, you won't be disappointed. I can't speak for the 2nd or 3rd generation of the pattern/model but I've never held a bad one from the first generation made in the 70s.
Just like many here, I too am an accumulator and like you Ed, I have many sub collections in my accumulation.
