mains, 23 inches
G-1s roughly 4 inches each so 8
G-2's roughly 12-13 inches of bone in those splits gross each so 25
G-3's roughly 8 to 9 inches so 17
G-4 2.5 (rightside)
G-5 3 (rightside)
Cir roughly 16 or 17 per side so 33
inside spread 16

Also, I cant tell if that is a g-4 poking out on the end of the left main beam or if thats just his camo shirt coloring looking like a tip of a tine. If it is I would add another 2.5 inches or 3 to the gross score.

150.5 gross???? just a guesstimate from the photo
