Hello Whitey my old friend,
The calibre is most likely 0.461" Gibbs as has already been stated by SKB, but it could also be 0.450" No.2 Musket also a very popular target rifle round at the time, and chambered in many of Gibbs Rifles. (Brass is still available, but not cheap, but then, what is these days?)
I don't believe that Gibbs ever made a 'Cheap Rifle'. Gibbs, (an International Rifle Shot himself) believed in quality.
Kirtons book is very good, Winfers are possibly even better. The volume relating to Gibbs, (Volume 2.) is not as thick as some other of his other volumes, but it is worth every 'Penny' or 'Cent' you will have to pay for it. Provided of course, you can find a copy in the first place.
I've never known any books become so hard to find, in such a short time after publication, as those by Wal Winfer on British Single Shot Falling Block Actions.
The reverse prone position was, perhaps, more popular in Europe than in the USA. But, both Sharps and Remington, provided the option of using sight mounts at the front and the rear of their rifle butt stocks, on their Creedmoor target rifles.
