Thanks guys!

I don't know but there is something about shooting with open sights that triggers some strong primeval feelings & makes shooting through scope like watching TV - accurate but kind of surreal.

Point is, I have a soft spot for iron sights - there is a sweet memory deeply imbedded in my mind of my first big game taken with borrowed Ferlacher double in the snowstorm with silver bead. That memory was fading away through years but remaining that strong so I have obtained this double deliberately to keep it up. Now the sights are catching up all is as it should be.
