Don't think there are many airguns with brakes......
Hyscore Repeater?
Currently looking for Baikal Makarov pistols with the following prefixes to the serial number: 98, T01, T09, T21, T22
Prefer boxed or cased but will consider loose examples too.
Thanks for your help
One of mine had a brake.
It was a Brocock air cartridge revolver when they were legal. It had been converted to .25 cal and as a result the engine became too powerful and the pistol had to be modified to reduce power - stay legal and all that. It was done by filing a shallow curve groove into the start of the barrel - the point where the rotating cylinder mates up with the barrel. That allowed some small escape of the compressed air. Result: legal power and unfortunately lots of noise. This could have been a fairly easily reversible modification.
I think/know I've said this before on here, but there's not a lot of activity so I make no apology...
