dbahan - thanks for joining us here on silver-collector.com…since we live in the same town it’s sure gotten to be a small world! As many of you know, I consider Mauser to be among the finest late 19th c. American silver, bar none, and have been collecting it for years…so I know the unicorn. Your unicorn is at least very similar to, if not identical to, the common Mauser mark. I have never seen “England” used in conjunction with the Mauser mark, and I’m not aware of any Mauser being produced outside the US. Are there other marks on the item? I don’t think I’ve ever seen any Mauser with just the unicorn and not the word “sterling”. Most Mauser holloware has four marks: the unicorn, the word sterling, 928/1000 FINE, and a pattern number. Most flatware has the unicorn, “sterling” and perhaps a patent date.
In any event I’d say its not Mauser, and without other marks, probably not even sterling. I’ll take a look at some of my UK books, who knows, perhaps there was a unicorn running around Jolly Ole England…
