[78-L] Regal 100-200 series

[Han Enderman]

Ebay item # 380107844079 shows Regal 201 by Ruth Etting, mxs 11064-65 (11 Dec 31).
Regal 225 & 233 (1932) are in Rust's CED.
Barr's Dating Guide mentions 101 8/31 & 218 2/32.

I have not seen this series before, so I assume it's fairly rare (apparently the final Regal series). 
What is its range and intention, and is it included in full in the Plaza-ARC dg?
