I can only agree with PeteM.
There is no design flaw in a Meriden and those that pass the sound ones by will live to regret it.
As to the status of Smith vs Meriden, perhaps the engraving can be faulted on the Meriden. Remember that they were selling through Sears & Roebuck.
The basic quality, of a good quality tool, was there and perhaps the Smith has a tad more cache than Meriden.
As to the American side locks, on today's scales,I would say---Smith, Meriden and the Crescent.
Best,
John
