Looking for info on my newest addition De Leon S 12 3/8" overall length

[WD Bob]

I've recently purchased a group of knifes from a guy, there is one giving me trouble finding out any info about it. First off it's a De Leon S not a De Leon A - B A 1 is on the back side of the blade, it has brass pins in the handle along with a brass bolster. Blade is 6 7/8" long x 1 5/8" wide. I love the knife and it feels great in my hand, good balanced weight. The handle looks like black micarta (not sure of spelling). A portion of the blade stock runs through the handle and is extending beyond the heel about 1/2" in a > shape. Not that good with knife anatomy so bare with me. I would like to value this for my collection but I can't even find info on it. Does anyone know what direction to go from here? ? ? Thanks
