which 4mm r-t-r wagons represent pre 1923 types

Feel free to rant some more.  I always learn something when you do.

 

I'd only be repeating myself which would become tedious both for you to read and me to write.

The Dapol 4 wheel rectangular tank wago looks to be a reasonable representation of a 1907 RCH design.

I was thinking of using a Dapol 9ft wheelbase chassis, just because that's what I have to hand. I also see that my link in the above post didn't work, so here it is again.

 

Check the length over headstocks. The Trackmaster/Tri-ang wagons are only 16 foot long (scale) which compromised many later models in the range. The L & Y van had a left hand brake lever on one side, though presumably this was altered later and possibly the roof hatch removed? I believe this e length is correct for a Dia. 3, but it's a long time since I built mine, so I'm not 100% sure.
