I have looked through all of Bruces's books and it only shows very early ones, does anyone have photos of the non-generator covers there are quite a few differences, thank you, Bob

Pictures of the front timing covers would probably be in one of Gail Rodda’s T parts ID books. Lang’s and others use to sell them but I don’t know if they are still avaliable. Maybe someone on the forum has one but I don’t. Hope it can help.

I looked in Gails book, not in there but thank you, Bob

thank you, I found it on the old forum, Bob

Smaller hole of the ealer ones
John F. Regan on Thursday, January 16, 2014 - 01:20 am:
There were at least 6 unless the early water pump car had a different one and then there were 6. The factory number of 690 came later and the D suffix would indicate then 4 of those. 1910 used a coil spring fan tensioner, 1911 used a vertical bolt tensioner, early 1912 oiler timer used a cover with no oil filler hole, 1912 and later used the cover with no generator mounting, 1919 then had a generator mounting...not sure what happens in the middle... and then the last one had no adjuster for the fan at all since it used the eccentric.

Some pictures - not saying the1915 is different was just ID'd as a 1915

Somewhere in the development of these, the following changes were made. They are not often shown in photographs. The earlier ones had a double wall around the camshaft hole which dictated the use of a felt seal to be stuffed in the hole. Later versions opened up the hole so that a proper oil seal could be installed, like the ones we use to replace the second incarnation of the felt seal. Sometime in that development time, the grove for the crankshaft seal was changed to accommodate a wider seal like the generator style cars used. These changes are not as noticeable as those made to the oil spout.

They made a change in 1915 that I like, and doesn't appear above I think. The 1915 still has the short spout like a 1913, but allows us to use a modern camshaft seal. The longer spout came about 1917, which allows the owner to pour in oil at a faster rate.
