I have recently obtained Ben Taylor's prototype FWB Sport 124 with a Gas Ram fitted by Ben
A real 'One off' made for FWB as an experiment.
As previously mentioned, My TDR is rare too, Hydrographics have only made 10 .177 dipped ones and mine is the only BTAS regged one out there
My Cyclone and RWS500 will be rare for a while, soon, as I am having the first GinB stocks made at the moment
Cheers
John
