Roy the chipguide doesn't give any info just says Ca. So maybe they are from Chicago. I just started to build the set on what I found and what listings I have seen.I think I have seen recent comments about the TK being from somewhere other than California.?Would be nice to know,so I can properly ID. These chips,that I like.Thanks for the news report.looks like the initials of the chips on these names of the arrested.Torrey. Any help on ID. Would be appreciated.
