The answer is "no." Here's a composite photo of a James MacNaughton round action double rifle recently offered by Griffin & Howe.

This rifle is a contemporary build chambered for .300 H&H Flanged.

And here's a pre-WW2 MacNaughton in .303 British sold by Sotheby's last August.

This is an antique MacNaughton .303 currently offered by Schwandt Classic Arms.

Finally, here's a look at the David McKay Brown .470NE that went to market a couple years ago.

Just a medley of Scottish round action rifles. Get out the single malt. . .
