John,the top set are 92 0/8 Bull,circumference at horn base 16 6/8 and 16 16 2/8
Length of horn 30 4/8 and 28 4/8 ,total 92.

The cow at the bottom had 13 inch circumference at horn base and ended up 92 4/8 ...
So the cow ended up bigger by 1/2 of one inch..
Very deceiving especially when in the bush stalking one.
By the way good guess on size and other details,well done.
