No makers mark on my ss 4 blade prop. why?

[Kylemurr6]

I have a pristine 23p ss 4 blade I need a steeper pitch prop I have to much hole shot not enough top end in my95 17ft range with a 87 xr4 150 black max. How am I supposed to sell or trade my prop if I cant define a maker? All it has is 23p stamped into side. Someone tell me what I got,and why not labeled
