Most English vintage doubles have smooth non textured ribs with zero anti glare qualities, why...?...

Makers from other countries like Italy, United States, Germany and France textured/file cut the ribs for anti glare... Or were the file cut ribs meant to cut down on heat distortion rising from hot barrels....?

Is there a reason the British makers did not texture these upper ribs, especially on the high end guns they made....?

Yes, I know we joke about the British Isles not having any sun shine, but what is the real reason....?....Or is that the reason, does anybody really know....?....Was it purely cosmetic....?...

Best,

Doug
