Carb Overflow Tube

The early Dream motor ( I have three 1960 engines) vented from the rear breather tower just above the rear drive sprocket.

I have looked at the page in the HONDA parts book and near as I can tell there are 3 holes as I see 3 tubes from somewhere.
Assuming that 2 are from the valve guides I figured the 3rd one was from the top of t he head .
My DREAM filter has 2 holes where I'd expect the valve vent tubes attach.
So where I suspected the DREAM had a tube from the top of the head to the filter is the reason I wondered why a DREAM engine would go to the filter but not the CB/C:L72/77.
Appears the 3 engines did vent to the open air but the DREAM didn't vent through a hole to the right side of the case.
Or did it?. .........lm

The hole I mentioned is not the one that the case with the round tower but the one that is behind the sprocket area.
The fact that HONDA DID install that carb overflow tube on the DREAM is vexing as none were installed on the CB/CL72/77 carbs at the plant. ???????????????. ..........lm

LM?
