Here's a strange one that i've often wondered about?

Looking back in an old dynamit nobel catalogue this little jewel looks interesting. I've never seen one in the wild or have ever heard of anyone having such a beast. Apparently you pump the cartridge up put a .22 pellet in and get up to 50 ft pds out of it. Did they ever even make it to production? Interested to see if anyone here has had one.

That’s an old Brocock. All their airguns used to use a separate cartridge.
