I have an 18s Waltham Wm Ellery KW from 1866 (serial # 254052) in what I believe is the original Hunter case, which is marked "L.A.S. PHILA". Case # is 225. Could someone identify the maker? Thanks.

Hey Eric, that's a pretty old Will Ellery. My trademark book is in the mail. If someone else doesn't supply your answer before it arrives, I'll find out for you.

I have nothing showing on that case.

I just did an online search and found in an 1860 Philadephia directory a listing for a Louis Scherr, watchmaker. Searching that name I found that Mr. Scherr's middle initial was indeed "A" and that the family firm was still in business in 1899 as a jewelry, watch and dental supplies jobber. So perhaps this is the L.A.S. on this case?

I saw that name in my book but no middle initial
got me thinking it was not him.
BTW nice watch in any collection.

Thank you, Peter.

Sounds like you solved your mystery !!
