I may have posted this before and if I have please forgive me;the mind is a terrible thing to waste!
I've had this now for many years and whomever I have showed it to that is knowledgeable on Case items is stumped.
It is a Case Tested XX letter opener with a dagger shaped blade and spey type folding blade. The handle could be described as a tapered coffin shape(or a trapezoid sleeve board);the handles are celluloid or something approximating it,and the advertising is for," Hanley Co. Face Brick" whatever that may be.It is in pretty much unused condition(I don't like the word "mint";that should be reserved for candy). I have never been able to find a pattern number or even an illustration of another one.Does anyone have any information? It would be greatly appreciated.
