USA TV with European Bezel???

[bgadow]

I was sorting some Sams the other day when I came across these 2 sets featuring the "European" bezel. On the left is a Curtis Mathes #7323 (Sams 468-1, 12/59) and on the right is a Hoffman B3683 (Sams 477-1, 3/60) Both sets use the same crt, 23CP4. My GE Essential Characteristics book states they use a "molded glass implosion panel attached to face" which is not uncommon...and is a fancy way of saying, I think, bonded safety glass.
