Oddly........

Doubles do come up on this site, last year or rather, a couple of years ago there was a 12 bore in great nick and another dr in 500 express, chap wanted 5000e a piece.

Also, though all I could ever do is copy pics for you lot, the gun mags here have some doubles sometimes AND very affordable spingarda's.....which are punt guns.

Armi mercato is one of the best mags.

Note that on armiusate.it someone is selling a Holland royal double rifle.

Cheerio
