I finally got a little computer time today so I am posting. I think these are on the RARE side. I just submitted them to the chip guide. I have had both of them for 20+ years. I think they are from the 50's or older. Sahati's was open from 1945 to 1958 so that one is a no brainer. Barbara Canon told me that back then when Harvey's or Sahati's did something the other one followed immediately, so I think the Harvey's is from the same time period.
