Wico was a distributor of gaming supplies. They never made chips.
They bought out Langworthy and the HHR mold. Wico ad chips on the HHR are common. HHR molded chips have always been made at Burt then AS.

*Chipco actually bought out the Burt Company. They sold the old molds to AS. I think John Kendall told me he made the Wico HHR ad chips.

Wico went bankrupt pretty quick, maybe a year or so.
GGS is the key to the Langworthy, RTP, and GGS companies. They owned Langworthy and a large chunk of RTP.
The chips you are showing are RTP.
GGS got the WICO assests in the bankruptsy, as far as I can tell. HHR went back to AS, not sure why or how. Maybe Blanchard will see this and tell us more.

The chips you are showing are listed as WICO because they sold, not because they made them, same as older HHR is listed as Langworthy because they sold them, not because they made them.
