Hello Jim and thanks for responding! Yes, this is definitely one untapped area of research/collecting that I had hoped someone might have more info on. I would love to research/collect info on this area, but my time of late is so limited.
I do hope to acquire Sim Comfort's naval weapons book you brought to my attention, Jim (Thanks!), but am still waiting to see the rather pricey volume come down to match the world economy! $300 is a little much for me
. I found the Pitt Rivers site on accident, but they have some pretty cool pieces in their collection and all correctly identified, as far as I can tell. They had an amazing chopper I was tempted to post on the Ethno site. Very fascinating item...
