Dick,
That R11 was very nice indeed, but, it was set up for a right handed individual, which, I am not.
As far as I know, that is the only single double trigger Darne that escaped Europe. Something else to keep in mind is only US customers could buy an R11-people in Europe didn't have the choices we did, here.
Use it in good health, I hope the notion of your passing is quite premature.

Best,
Ted
