I figure 140's as well. The way I guesstimate is you automatically give him a 100 b/c he is at his ears but justan 8 point so that deducts from the width past his ears. I would say both G 2's are around 12". That gives him 124 then G 3's look to be around 8" which gives him around 140. He is awfully symmetrical so I don't see much deductions. This is how I judge it in the field anyway.
