Article outlining different Mamod variants?

[cncmodeller]

Hi, Is there an article on here that describes the different Mamod loco variants? I'm well aware of the original one but am a bit lost on the more recent ones, I'm sure I've seen one with what looks like Square cylinders that appear non oscillating. I have a plan to make a batch of Rye and Camber Bagnalls using the slide bar covers to hide the cylinders.

My Topic here covers the first 3 piston valve locomotives which came from the current Mamod Railway System - http://gardenrails.myfreeforum.org/about6347.html

Then followed the Brunel (plenty of Topics on here cover that model), and a revised piston valve cylinder is now fitted to the Mark II Brunel, and the 2015 Thomas Telford when it is finally released.
