Ok people, I have a couple of questions regarding the "guts" of the current production Heym boxlock SxS double rifle action.

Do these rifles have.............

1...Coil or Vee mainsprings?

2...Bushed strikers?

3...Rebounding locks?

4...Intercepting sears?

5...Breech pin or stockbolt?

I'm hoping New Guy and others can shed some light here.
I've never had the chance to check out the locks on the Heym doubles.
TIA.
