I'm trying to find the part number/name for this part used on Sega games built in Japan (typically those intended for the Japan market) from the 1980s/1990s that use the Asahi-Seiko ADD type over/under coin door.
It's a metal type piece that is placed in an unused coin slot, usually the left-hand side.
I asked Asahi-Seiko in the U.S., but they don't seem to know about it, so it may be a Sega part.
I looked in several Sega manuals (it can clearly be seen in the After Burner Deluxe manual) but they don't break down the parts down to the individual door parts.
Any ideas on a part number or what it's called? I need a couple of them.
Thanks!
