My apologies to you Gene. I guess I jumped to the wrong conclussion regarding your posts. Chasing Id's on some of these old chips can sure lead down some slippery slopes. All of those chips I have seen appear to be well used so they may have made a broad circuit. For now, I am going to put one under Whitey's in San Diego and one under BPOE-Montebello and have both bases covered. Sorry for the mis-understanding and best wishes,
Butch
