470R:
I'm sure you are correct about that rifle being a Rigby, however I personally don't regard it as a "Gun Boo Boo" of any significance. At least it was a Brit sidelock double! That's pretty good for Hollywood I reckon!

BTW, thanks for the welcome to the fourseventy club. Hope I can live up to it! You will notice I refrained from posting details of the new acquisition till I had proven the rifle in the field: too many armchair-experts on this forum already!
