Assuming # 123 was made before # 247, then it had to experience provisional proof prior to 1887 also, so where is the number "12" stamp to complete the pair? First, after the Lion rampant over gP, the sequence seems to be out of order. Next in line should have been the view mark of "crown" over "V" followed by the previously stamped bore diameter. Was there a different sequence during the 1887-1896 period?
And is there a possiblity of equating the trade mark number to a specific year?
Kind Regards,
