In 1993 Simon Hughes, author of British Mining no. 17 "The Cwmystwyth Mines", had a second edition printed with an extra page of introduction giving an update on the site, and text on the bottom left of the cover stating that it was in aid of the Hafod Church Restoration Fund.
I have two copies of the 1993 edition. One has a somewhat greyish cover photos and the other has a much more distinctly black and white version of the same photo. The second copy has a xerox of Gus Horsley's "Caver's Guide to Cwmystwyth" and his survey of Lefel Fawr and Kingside Adit loosely inserted. Gus's guide and survey were originally published in Teifi Valley Caving Group Journal no.1, 1988.
I don't know whether my copy with Gus's guide and plan is a one-off insertion by a former owner, or whether lots of copies were sold with them inserted but I *think* that I once saw another copy with Gus's guide and survey inserted - which suggests that lots of copies were sold with them inserted.
Please could aditnow members check their 1993 copies and let me know whether their copies do, or do not, have Gus's guide and plan inserted in them?
Might be best to pm me via aditnow.
Many thanks in anticipation of your help!
