Happy Halloween All!

For those not out trick-or-treating I have a question regarding a piece
shown me yesterday.  It is a triangular pendant, probably pewter, about
2" on each side.  When found in the soil there was evidence of a chain,
but the attachment point is gone.  At the top of the triangle are the
letters "CFB" and at the angles at the bottom are "&" and "L".  The
piece shows a nurse or nun tending to a person in a wheelchair with a
bed in the background which may have someone in it.  The image is not
clear enough to determine what the wheelchair looks like (thus dating
it).  At first I thought the CFB stood for Clara Barton, but her middle
initial was "H".  I've googled it and checked out a few related artifact
books, but nothing.  The piece was found around Wilton, Maine, but have
no specifics.  Any suggestions would be appreciated.

Thanks,
