That's a .30 Browning with a BFA that's lost its yellow paint. Mind you, the notion that ANY paint could cope with the heat output of a Browning was pure wishful thinking! We got rid of the UKicon's last service Browning .30's when the last Centurion funnies and Ferrets went and a couple of years after that they were used as an 'exercise tool' just to use up the large stocks of blank. GREAT guns and probably the last of the true fitters guns
