We have done a number of videos recently on various different Pedersen long guns (the PA rifle, the Japanese copy, shooting the PB rifle, etc), but there was one version that I have not covered yet (aside from the US trials rifles). That's the Vickers factory PA carbine. Only a small number of these were made, at the end of the Vickers-Pedersen production run.
The mechanism of the Pedersen carbine is identical to that of the rifle, the carbine simply has a barrel about 2 inches shorter and a cut down stock. These would have been used by cavalry units or by sportsmen wanting a slightly lighter and handier rifle. It certainly does look like a sporterized rifle, but this is the correct original factory configuration.
