Thank you for the excellent and useful feedback chaps - enormously appreciated and I have already learnt a lot from this thread. I am trying to purchase a Reilly 10 bore (have been for 2 yrs now) so will seek to post up those pics in due course.

Gordon - appreciate the offer but the gun actually came with an original, two-tier Reilly case with original label so I am sorted out presently. Where are you in Nor-Cal by chance as I lived in San Francisco/Palo Alto for 6 yrs - absolutely loved it and miss it greatly.
