I own the attached HK-663a SCD celebrating the 25th anniv of Chicopee, MA. Have looked around a bit, I see that there are quite a few similar SCDs, many of which have a "FOB" type setup since I believe most were originally hanging from ribbons. My attached "Winchendon, MA" item dates from 1914 and while coated with a wierd white metal, it does appear to be quite similar to the HK-663 piece (and perhaps similar to HK-666) based on reverse design. My HK-663a piece does have bronze peeking out from behind the silver coating similar to a HK-340a piece. Does anyone have any clue as to how many different pieces like this are around? Just seems odd to me for the remaining similar pieces to have been excluded from the SCD collection given the two that are listed.
