Yes, I know, I uploaded them yesterday, but the tracker needs to tell us the file that is missing

Should this use 4551a or 4551b?
All the assemblies uploaded yesterday should be Unofficial_Shortcut, not Part

There are a two more assemblies with different push rods, do you have numbers for those? Or make a/b/c?

There is one more assy listed at BS 73354, and it seems to be an earlier version than 64665.

> How do you tell them apart?

Have a look at 4551a/b/c

a ist the oldest
b/c are hard to tell as it seems that c was in use also pretty early, but I do have Thomas trains using the b version. Although there are pictures of the Thomas bases using the "c" rod.
Furthermore there was a technical change as they stopped using the "return-To-Zero" hitches. My Thomas bases have loose hitches, the earlier ones have the RTZ hitches. (This is not visible)
