I only did my course early this year, and although I was aware of Andy's condition at that time, he gave nothing less than 100% into that course when many others in his situation would have perhaps just gone through the motions.
There are few people in any trade that are known by all the others for being a 'True Expert' at the top of their profession. Andy was exactly this to the leather cleaning and restoration business. He will be missed and remembered everytime I carry my box of leather tools into a house.
My condolences to Andy's family and to Judy.
