Gents, thanks for all the interest and you'll be happy to know there are more like you beyond this forum. This will be some kind of major tome and no doubt will end up easily costing $100 +. It's not just the production costs (which have been estimated in 6 figures) , but shipping and then distribution. For all the interest various museums have indicated they usually follow with "of course we have no money". It just seems to be too limited a subject for them although wooden fishhooks or woven baskets from East La Dee Da get the full treatment. Guess there's weird niches, then there's weirder niches.
As for the British Government they are keeping arms length because the Gurkha Pension system is so badly handled. The Gurkha Welfare Trust folks have 3 separate groups who don't see eye to eye. The government of Nepal is a trainwreck. My first contacts with the government of India were less than beneficial and then they got me mired in a system that makes no sense. The US govt has zero interest. There are a lot of Nepalese Relief societies but they are massive swamps of disagreement and very political. I had one group tell me they certainly wouldn't want anyone thinking the Nepalese had weapons or were once fierce warriors. Guess they never met a retired Gurkha.
It is all frustrating but I continue to send out inquiries and network till I find the right people. Somehow, someday it will get done. Have faith, I do.
