Thanks for suggestions folks.
I think I have now cracked it.
The desired font seems to be msbm10.ttf
I down loaded this into Windows from Sourceforge (works also OK in VA
with Netsurf), and used !TTF2F to convert to RiscOS. Seems to be sorted.
I had previously loaded some pdfs into Riscript and got partial fonts.
cheers

I have a problem with set theory notation - and can't find a
(RiscOS) font which reproduces the 'open' R, C etc shown at the end of
the table in the following link.
Techwriter itself doesn't include them in its symbols palette.

Any ideas anyone?
I have an open serif font, Mairo.Open which is similar but e.g. C has a
thicker line on the inside of the curve than the outside.
There must be a better match.
You could try this, it is a "free" font (GPL) with permission from its
author Roger White to use it.
Here is a picture of the characters:

Here is the font in RISCOS format:
