Dennis,
There are several legends behind the forget me not, but it has apparently been popular in Germany and England for hundreds of years, apparently it was the sign of Henry IV of England. The other "marsh mallow" is a good match also. Let the speculation continue. I looked up Myosotis on line and apparently this flower is also indigenous to the States especially where early rifle building was occuring.

Joel,
I would agree that the 4 petal flowers with the smaller petals in between are edelweis. 2 of the JP Beck rifles here in the Library have that finial, and I have seen a Beyer rifle with the same. Kline also had the edelweiss on his patch box lid covering the rivet. I agree, as you have said speculation.
