While just messing around in my shop yesterday, I came across two loose rear 
engine housings in a box. Thinking that I would relocate them I accidentally 
looked at their timing scales. To my surprise, cast right into the housing was 
a 0 to 16 on one housing and also cast in the other was a 0 to 18 scale. 
Further checking of some engines identified several with the 0 to 18 scale. These 
must have been all for 140 hp engines although I can't prove it. Also of 
interest is the fact that both types have a 3817672 number cast in them. That means 
we have two different castings both using the same part number. Thus the 0 to 
18 must be a revised version.

Of course we know the turbo engines all used a rivited-on timing scale of 0 
to 20 with 0 to 24 being obtained by going to the end of the attached piece.
