My Hamilton 950B has the serial # J306XXX, and according to the serial number list I checked, is from circa 1965. Mine came with an original melamine dial. Your 950B has the vitreous enamel dial which is much nicer. I suspect yours might be older than 1963. Hamilton phased out vitreous enamel dials circa the late 1940s. So I suspect your watch could be earlier than 1963, or it has been significantly upgraded with a new vitreous enamel dial. Nice, in any event.
An 18-karat twofer weekend in Dallas and Fort Worth. Sleuthing around for a "conspiracy" clue on the grassy knoll and at the sixth floor window in Dealey Plaza on Saturday afternoon. November 22, 1963 Taking in the Fort Worth Symphony Orchestra's opening concert season performance at Bass Hall on Sunday. Forgot to include a few photos of the Water Gardens enjoyed after the performance.
