Dudley's Auction & Estate Services are very competent at what they do. They know the values of just about anything you may need appraised and they also do Estate sales.
You can always find a fair deal with them and they are very professional at all times. The estate auctions/sales I have gone to that they have done have always been very good. They will also try and find something you are looking for, say you need such an item if they happen to come accross it while doing business, they will give you a call and let you know that they have one.
