Very nice! I love watching the project evolve - keep posting photos! Are you planning to have an over comb tang extension? I echo the .22WMR idea...
I seem to recall that Peter Hofer made a one-off once. Don't know about Thys. If these are going into production though, well that is something special and unique!
I wonder if Swarovski could be persuaded to make a limited edition scaled down scope for the rifle?
