My old physics teacher used to say all smart people are the same, while stupidity is always original. This doesn`t mean that everyone who isn`t burdened with special knowledge is foolish. It's just that sometimes amateurs break into the gun world with completely unreasonable, at first glance, ideas. As a result, very original actions appear. Some of them turn out to be quite workable and bring a lively variety to the boring and conservative gunnery

This is very interesting, especially for anyone interested in mechanical devices, maybe not so much for collectors of double guns.

Thanks for posting that, Robertovich. Most interesting mechanism.

That is a fun item. I did enjoy the utube displays, too.
