In the USA this revolver is marked Remington and 1875 but UK versions have Sheridan and Cowboy.
I’m guessing this is because in the UK Remington have a marketing deal with SMK and this is a Crosman product.

The UK markings don’t dominate the gun which is a good shooter and a lot cheaper than the 7 1/2 inch Umarex.

I’m not keen on the Schofield lettering on the barrel of that gun but my view is if that’s the way they make them you put up with it or pass.

When you are shooting you don’t normally read the markings on the gun much!
