Found these three paint sploches on the diffy....center is red, left is cream or yellow, right is green. What do they mean?



Picture didn't post, but the paint is on the diffy cover.
 
Extracted from a collection of abridged Triumph TR3 Service Bulletins published and sold by TRF (RFP57):

The TR axle ratio can be determined by visual examination of the rear axle cover.
3.7:1 ratio (37T x 10T) has a dab of green paint on the cover.
4.1:1 ratio (41T x 10T) has a dab of green paint and a dab of white on the cover.

I suspect this practice continued at least into the TR4 models. I'm not sure what the significance of the red paint is.
