And here's one more from Terry Moe with some, much appreciated and interesting, background...

Reed Pitchers Item number 125 

The blue pitcher is the standard 56oz pitcher.  The bottom is 3.5” in diameter, the height is 7 1/16” and the top is 3 5/8” round to round. 

The ivory pitcher holds 25oz and is not listed in the literature.  The bottom is 2 3/4” in diameter, the height is 5 3/8” and the top is 3 Ό” round to round. 

The black pitcher is the standard 19oz size with the unusual color from one of the art pottery lines.  The bottom is 2 5/8” in diameter, the height is 4 7/8” and the top is 2 Ύ” round to round. 

None of these are marked and I don’t recall ever seeing one which was marked.  They also came in yellow, turquoise, and orange.  They also came with lids.  The 19oz  with lid was called the syrup pitcher and cover and the 56oz was called the batter pitcher and cover.
