The E&A by anthony mount has this valve gear but he designed it with just one working eccentric driving a standard slide valve and that is what I did with mine. There was a Stuart Victorial done with it though again not sure if it was a dummy or real

It will make a great model, Willy.  Worthy of your skill.

I am looking forward to seeing one with that complete expansion gear working, and seeing how it performs.

I will be following along.

Unless you are going to be running the engine on steam at a decent pressure and under load I doubt the effects of the Meter vales will be noticable, certainly not if you are just running on the usual couple of pounds of air. That is why I did not model it on my large size Easton & Anderson, just went with the two excentrics, rods and linkages but only one working.

I am now making the pins for the motion rods and fittings  I have to drill small holes in the silver steel rod. I have somewhere a jig for doing this but can't find it so have done this with my old drill press.....vis....This is for use with a 57 drill and should always be there !!!

Beautiful engine you have made Willy, nice and peaceful runner.
Thanks to share all these studies along this build.

I had a look at the Meyer distribution in a  old text book I have, a challenge only for the brave...

More Models at the forum.......I also took my small lathe to demonstrate turning with the children ,and they took away soon pieces they had worked on.....untill the two electric cars started to blow the fuses and then melted the distribution panel in the building !!!
A good turn out by all the members and also a Maid Marion !!
