I understand from a recent post he has retired. I will add that I had two adjustable combs by him and his work was 1st rate, fair price and a very good turn around time, things all people in the trade should shoot for.
Mr Hollingsworth did a Super X stock for me late last summer. When I called him he said he has retired but will still do a stock or so for his "ole customers". Rather than give you his address you can call him at 270-646-4903 and see if he has the inclination to do a stock for you.
