Case Texas Special 4165SSP Pocket Knife Made in 1977. #L117.
I just purchased this nice older Case "Texas Special". It's a 3 dot (1977) model and the back of the tang is marked "4165 SSP". Nice deep engraving of the state of Texas, a longhorn and "Texas Special/1836". Tang marked serial number #2401. Never carried or used, but has some scratches on the bolsters from handling, cleaning, etc. over the years. White micarta handles and a thong hole in the bottom bolster. Ask for knife #L117.
