I was wondering where you got the attibution for the cord mold chip? I checked the club records but didn't find anything under STC or the owners name. The card you showed only mentions the Harp mold chips. Were both molds made by the same company?

So what are the odds that this chip could also be from the same place? While I am just having fun with you, the age of this chip is just about right for that club. But we will probably never know unless someone finds a cache of both chips together.
