I might just be that gentleman that Bob made the fuse cards for although a have a '68 coupe not a cab.
Attached is my original front and back. The part Bob made was beautiful and just like the original. It is on the car now.
I would highly recommend the quality. Looks like there are some very minor differences to 49er's including the part number, but basically the same.
As far as copyright, I am not a lawyer, but there are no references to the Mercedes name, only the part number.
