I think Swenson was actually an American. The later Paramounts had the one piece bolt and not the pinned bolt head like the Swings. These are closer to current RPAs but the cocking piece and trigger may need an upgrade to bring it to current standards.

For anyone interested in a bit of research on Robert Chombart’s work and his history and evolution of the Swings and Variants can visit here.

Some digging may be required here but lots of information.

Sadly Robert left us this year.
