I have just been looking at the very good photographs of the Airsporter RB2 that twocore has bought today on here (one of the best looking air rifles ever made)

One thing that I noticed was the HAMMERLI stamping on the barrel, just in front of the rifles serial number. I assume therefore that the barrels on some of these if not all of the Stutzens were supplied by this gun/barrel manufacturer.
Or was it only the .177 barrels that were supplied by Hammerli

Has anyone else an Airsporter with a Hammerli barrel and does anyone know why BSA were not using their own barrels at the time?

I have never seen any reference in the past to BSA buying its barrels from Hammerli
