I will make note of that in the California listing for those chips. I already eliminated the Montana listing.

It's good to know the source for all the monogram chip attributions in the ChipGuide, and I always try to list them in the California ChipGuide.

I think it is also useful to document how new information (such as the C. W. Rice records Jay has found) has shown that some sources are more reliable in their attributions than others.
