Jase, you should be aware that those red, white, and blue "LMs" are custom by Radioactive Spyder, not original versions. He is one of the experts at blade and scale swaps, and other customizations to scales etc. You can find examples of his expertise over the years on this forum.
Originals are *only* in black, or dark blue from BBS.
A PE black frn LM may be hen's-tooth scarce, but keep your eyes on ebay and BFE. A Delica 4 labeled SE Lil Matriarch would be less uncommon; a Lil Matriarch labeled SE should be next easiest to find. (To echo RadSpy, I've never seen a Lil Matriarch labeled example in PE.)
The BBS PE LMs show up regularly on ebay by other sellers, (BBS also sells them on ebay), so be patient and watchful and one will turn up for you. Of course you can then swap the blade into a Deli 4 handle color of your preference.
As a Delica fan, you should also check out the Tasman and Merlin Spydercos; easy to find used ones at low prices fairly regularly it seems.
good luck,
