My advice is buy it if the price is right and the condition good. The one that Historicbore mentions will be a machine made gun and can be found quite cheaply in the U.K. Proper hand built singles are every bit as well made as the doubles. I have them in 28, 20, 12, 10 and 8 bore; my 8 bore being by T.Daintith of Warrington. I can't really advise on price for the 8 but anything in decent order usually goes here for north of £1,000.
