My comments on the nature of the finish are a note to look deeper than the surface.
It's a neat configuration, and if it's in running condition it's a desirable hunting gun -- just look deeper than the finish.
I bring that up so that you'll take a closer look at the condition of the metal under the wood. Paradox guns were ideal for hunting in the jungle, and jungle conditions can be hard on guns.
Will you find rust or heavy pitting under the wood?
Will the head and wrist of the stock be sound and solid under the tangs lockwork?

You'll see!

Cheers
