Here are pictures of two watches, a Hampden Lafayette model in a 5 oz case, so marked, and a Waltham Model 1857 in what I believe is a 6 oz case. It is not marked with an indication of weight. The only markings on the 6 oz case are the serial number (3124) and Warranted Coin Silver. The Hampden case has a 5 in a cartouche; it's a Keystone case. The cuvette is engraved "Presented by Father and Mother to Son Hiram Mudge Miller April 17, 1883". I suspect that's a birthdate, and so it may be possible to identify Hiram.
The Waltham movement is not original to the case as I had bought the empty case in a pawn shop on the Eastern Shore of Maryland perhaps 15 years ago or so. I put the Model 1857 in there. You will note that the one case screw lines up perfectly with a mark left in the case, so perhaps the case originally held this model.
I scrolled through all the postings. The largest size case I saw was 6 oz. unless I missed something. Someone referred to a 10 oz. case. I did not know such a size existed. I have heard of 8 oz. cases, never saw one, but 10 oz. is getting to the point of not being practical. I'd like to see one.
Well, I found Hiram Mudge Miller on Find-a-Grave. He was born 17 April 1866 in Williamsport, PA. He's buried in the Pacific Crest Cemetery in Redondo Beach, CA. Given that my watch has the same day of month, I would say we found our man. He turned 17 when his parents gave him this watch. Thank you, Find-a-Grave.
I did a bit more poking around in Find-a-Grave. I find reconstructing a family tree something like solving a crossword puzzle. Anyway, I figured Hiram's middle name (Mudge) was a last name and that he was named after someone on his mother's side of the family, assuming she was a Mudge. So I searched for any Mudge in Williamsport, Pa, where Hiram was born. Sure enough I found a Hiram Mudge, who lived from 1822 to 1897; he's buried in the Williamsport cemetery. I suspect he was an uncle on the mother's side, not a grandfather as he was 44 when the original owner of my watch was born. This rapidly gets confusing, that is, tracing these lineages. But Uncle Hiram had a daughter Jean who lived from 1861 to 1936. If I'm right--and I think I am--that would make Jean cousin to Hiram. Curiously, they--Hiram Mudge Miller and Jean Mudge--are both buried in Los Angeles. They both went west. Since she is buried under her maiden name, I assume she never married. I bought Hiram's watch quite a while ago via eBay. The seller was located in California. It would seem my watch also went west. Thereby hangs a tale. Interesting what one can reconstruct.
I just received this one today - a 14-size Am.Watch Co. coin silver hunting case. It comes with a 7-jewel American Watch Co. "Bond St." movement. I bought it for the lovely case with very little wear, as I have a higher grade 1884 model that is currently naked. Unfortunately I failed to pay attention to the 1888 inscription and realized it would not work out for my ca.1890 movement, but I am sure I will either find a more appropriate movement one day or just enjoy this one as is.
Also, not too long ago, I bought a very nice 1-size Waltham in coin silver (plain-polished case on the right). The engine-turned 1-size on the left is one I have had for many years. Both are A.W.W.Co cases.
