Very astute observation David! That really does seem to tie in with the fascinating variables in concert with the numeric 7 as you have noted. Fernando has been instrumental in providing remarkable data on the numerics and markings that illustrate the importance of symbolism that exists on these blades from the Portuguese parlance. Clearly this is key with our topic on the thread we have going on 'Early Makers Trade Markings' and the history of the markings that occur on ethnographic weapons' blades.
This firangi of yours is perfect evidence for that topic!
Nicely done!!!
All best regards,
Jim
