From my recollection from talking with the late Henk Visser, the VP at NWM, Mauser & the Quandt Group......NWM sold the rights to the V40 during 1972 or so. From what I remember the whole package was sold to a US entity along with some other defense products......the weird thing is that I am intimately familiar with the V40 from 1967 through 1972. I have never seen a so called US manufactured V40......and I do not claim that one never was made. It just deosn't make much sense since the Vietnam war was winding down, and we were sitting on tens of thousands of them in the US and in S.E. Asia in Okinawa and Taiwan (the US Advanced training site stockpile). I never bothered to ask Henk who bought the V40 rights.
If anyone, Cadillac Gage or Bauer Ordnance could have made them, since they were closely partnered with NWM (Stoner 63A system licensee) and Bauer (Mauser commerical rifle importer to US & US Military subcontractor for rifle bayonets with capability to stamp out V40's). But knowing the end users for these during this time frame, the work was probably farmed out through what was left from Frankfort Arsenal's test support group (since the arsenal was closed down during the 1960's.) Phillie had the largest grenade fuse manufacturer located there.
Having one show up in Taiwan doesn't surprise me at all because of who had a large logistics facility there, but it doesn't make much sense on having them make them since the US was supporting the Nationalists so heavily. Technically it does make sense since there seems to be quite a difference with the firing pin arm and top end (maybe simplified by a couple steps......The US made version seems to differ in the paint....being a dull Olive Drab, versus the shiny epoxy from NWM.
If anyone has a Taiwanese V40 or US Made V40 with an inert fuse......we can find out more info, as I still have a contact who worked with NWM at Dynamit Nobel on subcontracting the V40's fuses. We can trace lot numbers to the manufacturer(s) of the non-NWM V40's.
What I do know is that earliest V40's had writing painted on the sides (mainly the inert training grenade). I have a copy of the 1967 technical prints, which I will post up when I figure out how to do it.
The technical prints show that the lot numbers HAD to be painted on the base of the grenade body for the HE model. The prints also showed the two different types of bandoliers......one a plastic "zip lok" style and the other a plastic impregnated fiber style with snap hooks on the sling.
From working in the Middle East for the U.S. Government, I can say that as late as 1982, the US issued V-40's to certain security types.......and all were marked with lot numbers in the 1971 range. I also carried a V40 issued to me in Central America by the U.S. Embassy (grenades were defensive you see :nerd:. It was also a 1971 model, since I still have it mounted to a wall plaque.
Canada also had to destroy all their V40's in the 1980's...as they had adopted it. The fuses went bad, so they say....and several soldiers were injured when they had no delay on releasing the safety arm when thrown. There was an extensive report on the Canadian tests of the V40 which resulted in the detruct order. I will try and find it.
I have several dozen V40's and a couple V41 inert trainers in my collection. I AM looking for an original V40 rifle grenade adapter. I was supposed to trade with Henk Visser for one of his, but he unfortunately passed away before we could talk again.
It was a novel weapon idea that should have made NWM millions of Kroners, but I think something caused it to fall by the wayside. NWM's bullet through rifle grenade was a success in the market, but they also ended up selling/giving it to Mecar, with it being copied by FN as the Telgren in the late 1980's.
Anyone with a NWM V40 rifle adapter........who wants to sell or trade it.....let me know.......I will post the tech sheets when I can get home to a scanner.
I will also have several NWM V40 sales brochures to offer too in trade etc.
