thanks, I did a google image for those terms but didn't find a match. I found however a lot of Taito cabinets that were similar in many ways, the curved side and the instep on the front. Couldn't find an exact match though.
I've gutted and cleaned the can, unfortunately there were no identification marks.
Whilst I have your attention, is it normal for arcade cabs to be built with chipboard (low density particle board)? I hate this stuff and had previously assumed that cabs built to take a beating in the arcade would be made in plywood which is much stronger. I hate working chipboard. it is very weak and crumbles apart on the edges.
