Black Marshal, Centaure, three screw frame

Today a black marshal with a three-screw frame popped up at egun.
At first I do not believe that it is original.
What do you all mean?
Look at the loading lever, the front sight ...

Picture if I get the permission for it

Here are the pics





I think that the barrel looks shorter than usual for Marshalls, the shape of the front sight is strange (too pointy) and the end of the lever where it locks (on the part just under the barrel) is not correct....

Don't you thnik that is it "surprizing" that there is no pic of the top of the barrel (where ther inscriptions are) ?

So we are agree for the first step, that this is not an original?
For further investigation do we need the value of measurement of the barrel.

and the pic of the top of the barrel....

Why not ask the seller for these details ?

I wait for answers

The first owner said that he bought it in 1972/1973. It was not edited! Why is the frame not colored hardened? That gives me a headache! All versions, except stainless, have colored frames.
Maybe it is a 8"/ 5,5" Set with two barrels

The lever is also stainless at the 5,5" barrel

Only thing to do.... you have to buy this anomality for your collection

and here are the ultimative Marshal 1. Variation, 1. Subvariation very, very, very rar in black , also blued by the owner self......merde!!!
I could be spit the hole day for this .....sorry for my words
