Does anyone know of a shift knob with a four speed H-pattern and no reverse?

NO REVERSE FOR YOU!

Or a place that will custom engrave a knob (worth buying) with a custom pattern? I want to replace the generic plain orange plastic knob on the Zetor. It’s a standard H-pattern four-speed, but since it has shuttle shift, reverse/forward is on the column.

I want an engraved/marked knob, but without reverse in the pattern. I think it’s a 1/2" thread, though it may be metric 12x1.75...? I figure I can always tap a knob or embed a nut, but I don’t have engraving equipment.
