Well...
..actually the original poster asked about commercially manufactured and readily available .41 rimfire ammunition for the Vetterli rifles and you replied by telling him about the 7.5 X 53.5 centerfire ammunition for the early Swiss straight pulls.
I only wanted to show you that similar ammunition has been made more recently less than 100 years ago, it is no longer in production now but has been in use quite long with the M97 cadet rifles.
Writing to "CaTW" is of little use I guess as they probably do not even distinguish between GP1890, GP1890/03, GP1890/23 and the cadet cartridges, all these fit the older Swiss straight pulls and the M93 cavalry carbine.
GP1890 was improved with a new type of (non-corroding) primer in 1903 (GP1890/03), when production ended is not sure but there are cases around stamped up to 1911.
As in the early twenties the GP1890 became scarce the Solothurn ammo factory produced a number of lots in 1923 and '24, this so called GP1890/23 differed from the older cartridges as the bullets were no longer paper patched but NiCu plated like GP11 are.
The cadet cartridges had a 20% lesser charge.
Commercially available no not really but still sold in Swiss gunshops as collectors ammunition.
