The Case 3254 trapper came to me with no scales at all, but I suspect it may have had the yellow celluloid that was starting to go. (There are no dots hiding under the USA, so it is from the 1965-69 period.) I did have a shield in my parts collection that fit the liner holes, but as you can see, it was pretty beat up. (If you put a beat-up shield on a restored knife, you get a restored knife with a beat-up shield.) The scales are Culpepper's smooth "Sunset" bone.
The Robeson 66426 was missing one scale entirely, the clip had a broken tip and someone decided to bend up the liners just to make things more challenging (last 3 pics). But, this one only cost me 9 bucks, it did have the original shield and I am a total sucker for this pattern. I've seen it described as a cross between a dogleg jack and a gunstock. (Or, maybe a pregnant dogleg?) Anyway, I reprofiled the broken tip, straightened the liners and the new scales are smooth, undyed white bone (poor man's ivory?), that I left at full thickness, which I prefer.
So, the EDC herd has now grown by 2.
