Have opportunity to price and buy old and nice condition serial 995 J. Alfred Jurgensen time only hunting case small 46mm diameter 18k. Read that he was son of Jules and his work was as good. Serial 995 indicates about 1880. Only possible defect is setting. May not be bow setting. There is notch in rim at one o'clock that may be for lever set. I am familiar with bow setting in Jules Jurgensen I have and this one does not work. Lever not visible; may be broken. Did he use either bow or lever setting? Am I right with age of 1880? Photo is not mine of 1890 similar plainer version
of the questionable one.
