Thank-you very much Hose & silvermakermarks for your very prompt replies.
i am sorry if the photos are not the best. For some reason i was having difficulty and this was the best i could seem to get.
The letter definitely is a lower case “i” but is it scripted, if you will, and therefore i would have to agree that it is earlier than 1908/10. The two on-line date codes i have with this “i” show an oval lozenge (1883) and a shield (1806).
This watch case has more of a shield, but with rounded top corners. Hence my confusion.
The AB is too small to photograph, but the letters are block text with Sarif separated by a centered dot and set in a rectangular lozenge w/chamfered corners. i had considered Alfred Bedford and the timing would be right for 1883, but their are a number of Birmingham AB’s to be found, none with an exact match (e.g. differing text, no dot/chamfer, etc).
Again, i thank you for your assistance.
