Thank you Karl. A contribution to the gallery's running costs will be greatly appreciated, especially a recurring one of dollar or two a month. Extraordinary BSA that one. I've also never seen one of that vintage without the roll stamping. :)
If you enjoy looking at pics of old airguns or learning about them, feel free to drop in to my not-for-profit gallery of vintage airguns. It's funded entirely by donations from people who, like me, are genuine collectors and airgun enthusiasts. :)
