I don't see this gun as a bought-in gun from Beesley. The production #'s for the year this gun may have been made show 20 guns listed. The next year 14. They may have needed to buy in a gun but I don't see why. Components may have come from Scott.
The #'s on the gun barel do not jive with production #'s for Scott. They're from 16 years earlier.
The legend on the rib misses the date of Beesley occupying that space by 5 years.
I couldn't make out the "From Purdeys" that Beesley engraved on his guns. Is it there?
So what is this gun?
