Never seen or heard of the partisan model Sten! And you'd have thought that I would wouldn't you. I'm not sure that a barrel that short would re-cock the gun because by the time the bullet had left the v-short barrel, the gas would have dissipated to atmosphere much earlier than it should and in doing so, wouldn't have imparted sufficient energy to the breech block to enable the .......... anyway. Or am I being a tad pedantic?
