Allyne sent along some photos of this beautiful, I think 1940s, BSA, now outfitted with one of our 18″ straight horns. Great match.  Love that we can help folks add that extra touch. Thanks for the photos!

18" straight horn on classic BSA motorcycleAllyne fabricated their own attaching bracket. I would love to find a source for all-brass attaching brackets. I had some custom made at one point but they weren’t strong enough. Still on the case though.
