So basically, you're the expert (my better!) and everyone should believe what you say without you having to explain any further? Very interesting....

Sorry, you 'might' get away with that if you're Hamilton Bowen, Alex Hamilton or Jim Martin but nobody knows who the hell Barry Stewart is. That said, any of those men or a plethora of other gunsmiths would take that position. I'd expect any gunsmith worth his salt to explain EXACTLY what those differences were and why it mattered.
