Hi I'm trying to identify the following pocket watch movement it is in a solid silver Dennison watch case, UK Birmingham Hallmark dating 1915. I have no doubt watch and case are originally paired. The watch keeps excellent time and I am loathed to start stripping it down without good reason, to try and find more marks or serial number. The movement appears to be a 15 jewel separate bridge design with: 'US PAT 24 MAY 1904' being the only inscription on the movement. The centre / train bridge is quite a distinctive shape, but I have thus far been unable to identify its maker/calibre from various online reference sites or books, like the excelent Cooksey Shugart complete price guide to watches. The movement is 41mm diameter US 15 size
I'd be grateful for any help to identify the maker of this movement.
Many Thanks Jim
Had real trouble trying to use the insert image from URL feature, can anyone give me some tips.. .
