Mike, Gibbs themselves were actually a large supplier of Mannlicher rifles to the trade where they did all the work. Some were marked with their own name and many others with another retailers name or no name at all like my one, which is definitely a Gibbs as it not only looks like one but has the B suffix in the serial number.

Apparently Gibbs supplied more of these Mannlicher rifles in various forms as dictated by customers to the trade than anybody else. This can also be seen by the fact that most of these rifles if they have a makers name on the barrel will say "Shot and Regulated by .....) as that is often all they did.
