Sorry about the delay, I thought it was posted to me, but discovered it in an email this morning (summer holidays etc got in the way of searching). I have two docs:
Anglezarke and Rivington Moors - Archaeological Survey 1986 - published in March 1992 by Lancaster Uni (J Quartermaine) - This seems to have most of the SMR for the area included.
The other doc is the proceedings article you mention.

Email me on the address on my profile if interested and I'll forward them to you.
