Not that kind. Believe this is a NN THOMAS. Mustard glaze. They were installed on bow & arrow brackets. The line dates 1905-1908 range but feel something like this may be a later install especially with the crown design (see the next picture).

U-673 or U-671A range but dimensions are 6" by 4"

Hi Masson,

That crown design with the pair of "C" shape top rests came to be at least during the mid 1920s, pretty much superceding the "half-moon" top rest design that you found on your large New England Power insulator (as you also pictured in one of your prior hunts). Yours surely looks like a Thomas without doubt and likely is 30s or maybe 40s.
