Here are links to the parts breakdown files for the '48-'49 loco and the '51 loco. They will show you the differences in the models.
Here is a page that shows how the smoke unit is attached to the motor frame.
Finally, here is the parts breakdown for the smoke unit itself (bottom of page).

Thank you I have those files. I couldn't spot much of a difference besides the fact that the 51 loco has rollers and the earlier ones have contact slider shoes? So I will assume I have early variation A (which I heard there was 3 variations) But also no way to tell if it is a 48 or 49?
Thank you for the 2 docs on the smoke unit as well. I cannot seem to understand them it says 1 screw to get it away from the frame? But there is a lever under it and the piston seems stuck on it so that is where I am lost.
