Google turns up very little specific information on either of these devices, e.g. nil

The best leads I have are:
- The UTR 700 was badge engineered by Ferranti into FM1600B systems, one of which fetched
up at the Centre for Computer History, Cambridge, England; perhaps with documentation.
Also, as it was used in government systems some maintenance documentation may have fetched
up in the PRO, at Kew.
Are you sure it's a UTR700 and not a UDR700? The latter is a
'UniDirectional Reader' running at 700 characters/second. I've seen
them badge-engeered 'Solartron' too. I also have a Unibus interface
for them.
If it is a UDR700, I have the 'user' manual which includes full
schematics, parts lists, alignment data, etc. I did offer this to
bitsavers along with the manual for the HSR500 (bidirectional, 500
cps) but they weren't interested. Unfortunately the manual is nearly
140MBytes (my scanner software is very inefficient!) so too large to
post or e-mail, but I can snail-mail a CD-ROM or memory stick with it
on.
