There is always an extensive history behind these English guns, and that A. Hollis rifle really has one. I'm reading about a Scottish hunter in Africa back in 1847, with his 'Old Friend' a double barreled James Purdey rifle, however since he is Scottish he is becoming more partial to his two grooved J. Dickson double barreled rifle. That's what I like about the English guns, they have a history about them that is well documented.
There is a lot more information on Isaac Hollis then there is about Alfred. I cannot find the relationship between these two, whether or not they were related. Also, did Alfred Hollis build his own guns/rifles or did someone else build it, such as Webley & Scott. I'm still looking!!
All the best
