Gamekeeper Air Tanks - Seeking Info

[MAD DAWG]

I have at last acquired a Colchester Gamekeeper. I am looking for up to two additional air tanks for it. If someone knows where one or two of these might be found I sure would appreciate it. OR if these tanks (or their 'fittings') are some 'standard' item from some other application - would appreciate any information about what that other application might be, or any specifications for the fittings, and again, a source if known.
Thank you all, in advance, for your help, and Best.......!

Does your Gamekeeper's existing bottle have a brass thread on it?

If it does I would suggest you get a competent engineer to make a new adaptor that is fitted to the rifle to accept Theoben buddy bottles. When I had a Gamekeeper the brass threads had become dangerously worn.

I can tell you that the BSA Super-10 air bottles are NOT the same - even though the threads look VERY similar!
