A couple more gain twist barrels...

The Moschetto M91 is the carbine version of the M91 long rifle. Originally intended for the cavalry, it was designated Moschetto M91 d.c. ("da cavalleria")
after the introduction of the Moschetto M91 TS ("Truppe Speciali")

This uses the same barrel as the Moschetto M91 d.c.
And before anyone asks...
The Moschetto M91/24. The "pocket rifle". This is probably the nearest thing to those jokey "tanker" rifles fudged up from old Lee Enfields that was ever produced by a regular arsenal. The first version simply had the M91 rifle barrel cut down to a rifling length of 377 mm. Which meant that the faster twist end had been cut off, and it was a ballistic flop.
For the second version, someone applied a bit of thought before starting up the saw, and these had an M91 rifle barrel shortened at the breach end, and then an insert/sleeve made to attach this to a new breach. So the twist has to be worked out backwards from the muzzle, giving a twist at the muzzle of 201 mm (as already given for the Fucile M91) and 360 mm (3.25 degrees) at the start of the rifling, a little sharper than the Moschetto M91.
After all this, the Italian arsenal engineers must have been heartily sick of the whole gain twist business, and it is not surprising that the 7.35mm carbines and the Fucile M91/41 were designed with normal constant twist barrels.

P.S. If there are any mistakes in the above values, it is probably because I am getting confused as well!
