Thanks for posting this, Russ. At least we now know that the # 3 retard was 
real, for at least SOME distributors.

Scott, maybe I'm confused but it looks to me like there are 6 distributors 
called out on this page and only 3 of them are type 3 distributors. Or did some 
early type 3s use 111 dists? Out of those 6, two type 1 dists and two type 3 
dists had the retarded # 3 cam.

Russ, were there other pages that also showed advance curves for other type 3 
dists with retarded # 3 cams? Having all the type 3 advance curves posted (at 
least those not already published in the Bentley manual) would be a valuable 
thing, but if that's too much trouble, maybe you could just post the #s of the 
dists with retarded # 3.

I should also point out that the charts and numbers are all in DISTRIBUTOR 
SHAFT DEGREES, so that the 2 deg of retard translates into 4 deg of crankshaft 
angle, which is what we would see when looking at the timing marks. Four 
degrees would also be enough that we would be certain this was not just 
manufacturing tolerances. ISTR that 2.5 degrees on our pulleys comes to about 
1/4" or maybe a bit less.
