So what era were they brought in about 1900 1910 that’s what those ads kinda look like to me at the top of the thread
Beginning around the early 1900's initially but they had so many still coming in or in storage it actually took about 50 to 60 years to sell them all on the civilian market.
That is why firearms ads from the 1950's still had them for sale as in this ad from the Golden State Arms Corp in the
February 1958 issue of Guns Magazine.
The Swiss made about 300,000 of all their 10.4x38mm versions.
The Swiss started to sell their Vetterli rifles off to buyers like Bannerman's around the early 1900's.
When you include the Italian M1870 and M1870/87 Vetterli's in
10.4×47mmR, the number made is about 1.6 million rifles.
Before
World War I, Italy still had about 1,300,000 M1870/87 rifles still in their inventories, of which 500 000 got sold to a private arms firm, Zumino & Rossetti. These 500,000 guns are the M70/87 rifles then sent to Russia. In total, about 700 000 Italian Vetterli rifles got later converted to 6.5mm.
The Italians used their 6.5mm versions until about 1950 before selling the remaining 6.5mm versions off.
Frank Barnes reported in one of his books that surplus Vetterli rifles were still used in "surprising number" by civilians in the U.S. for hunting deer up through to about 1972.
