Y Felin - Nanternis mill was for sale at the time of my survey in 2012. It is turbine driven from the pond behind the mill. Some of the equipment has been removed so the drawings below are speculative and based on the parts still in situ and several other mills of a similar type. The gearing was  probably cast in the Cardigan foundry and is similar to Mabes mill and FelinWen both shown on this site.
