Smaller FP gas bottles

Trying to fit even a single 2kg buffer in bulldog is proving very difficult, be easier getting hold of a couple of smaller bottles

Anyone got about about? Im happy to swap for 2kg bottles, got 2 with twist valves, 2 fire extinguishers and 3 with no vlaves of any type

I have 1 cheap option. A 1.1 kg CO2 bottle.
And one expensive option, a custom buffertank, like in Bullfrog.

I have a 1.1k bottle for sale, lever top, make me an offer.
