I purchased a sterling silver spoon from a yard sale and I'm trying to identify it. The 3 markings are: "sterling", a script "D", and a capital "M". Based on research conducted on this site's encyclopedia, the script "D" indicates that it was probably made by William B. Durgin Co. which was later "absorbed" by Gorham. According to the Gorham date marks, a capitol "M" indicates that it was manufactured in 1880. However, according to this site's encyclopedia, Gorham did not absorb the company until 1905 and the date marks listed for Gorham do not apply to flatware. My question is, does the "M" mean that the spoon is from 1880? Or, what else could it mean? Thank you.
PS- I would post a picture of it but I can't find that option as the file is on my computer, not on a website.
