Maybe padauk?
I made some grips and a pump handle for a Sheridan Model H from this very dense hardwood. Left unfinished, it weathered in to a really nice deep burgundy color. Beautiful stuff.
so are you trying to match the wood that is there, a picture close up, maybe go with a laminate in a color that you like

they make a 3 x 3 x 10 inch piece
just an idea you have not supplied enough info yet

I put a piece in my basket and my was $15.47 so it is a little high and I'm in Washington state
I would be happy with $9.99 but sometimes you can't fight there shipping, UPS seems always a little high but if you need something and it is hard to find what choice do you have
in any case good luck and take care
