I am writing because I stumbled on an E-Sylum article about engraving styles and early medals. I had some great fortune recently and was able to purchase the attached 18th century silver life-saving medal from a gentleman that found it using a metal detector.

I have done extensive research in old newspapers and many other locales to try to identify the engraver of the piece. I have strong reason to believe it was done by Mr. Joseph Callender. But other possibilities include Paul Revere Junior and Joseph Loring. I am also curious about Reveres work and suspect that some of the work that has been attributed to Revere may have actually been engraved by Callender.

The entire story of the rescue related to the award of this medal is documented. The major rode 10 miles on his horse in 30 minutes to retrieve a doctor to revive a drowned child. I'm looking for any insights I can get.
