Gene,

If you can lay your hands on a copy of Wal Winfer’s Volume 8 British Single shot rifles you will find at pages 299 to 300 photos of a Scott built double Holland and Holland rifle in .360x 2 1/4 “ Express. It is fitted with the patent gas checks and bears a patent use number.

I know this was not a “ big bore” but it goes at least some way towards answering your question,

Keep Well,
