Original European made pommel pistols for the Ottoman /Balkan market generally came in / were sold in pairs (so as to fit the saddle holsters) so if they were together for awhile the same sort of wear would be normal.
The wire repairs on both barrels are slightly different (thin wire top, thick wire bottom), but these are still suspect - might be late 19th century touristy-trade items and not 18th century originals.
More detailed photos (like the lettering on the escutcheon plates) are required.
