Once more, the old dinosaur rises again…!!
With my friend Jean Huon, we had the opportunity to examine the gun (which belonged to a local collector) in the 80ies.
It was obviously a test “vehicle” to look after the possibilities of obtaining MOBILE INTERCHANGEABLE CHAMBERS, so strictly nothing to do with AT or suppressed rifle.
Unhappily, we had no silicon paste available in those years to check the internal organisation… and rifling. The so-called “silasten” material we use now was not in general use, except for dental practice…(!) and we only took pictures.
It seems that the idea was to explore the possibilities of diverse chamber profiles, without altering the first part of rifling, which was left unchanged.
Fede, if you have a patent in reference, we would be very interested in seing it, especially for the date and name of the patentee…
Btw, I would also like to know the origin of the corresponding (?) cartridge pictures affixed ?
