Just another quick update;

The original backbox had a serial number stamped onto the top of it (1st pic), so just for the sake of keeping this game as original as possible (and just to see if i could do it)  i decided to recreate it on the donor backbox.

The pics tell the story..
i took a scan of the original serial # printed it out onto paper and used that to trace it onto some masking tape stuck onto the backbox using carbon paper. Cut it out, masked off and a couple of light coats of black paint... DONE!!
