Have these four Miller Crow Foot Wrenches and would like to know how many other sizes were sold and also acquire the ones I don't have. The No. 7 is 7-1/2" inches long and the No. 12 is 14" long. Found the listing below in a 1913 Chilton Auto Directory.

That hints that the numbering relates to the shank length somehow.
Stan thanks for the input. If the number does equal the distance between heads the No. 5 is probably the smallest.
