Any one know of a appraiser in the Phoenix, AZ. area. Could be from out of state too I guess. I have a friend that lost her dad. He was a collector of HO trains. There is lots brass and lots of rolling stock. I have not seen this yet, but I don't have a feel for HO equipment, so I am looking to get it appraised. This is a very large collection, fills a 10x10 room. Boxes and more boxes full of HO goodies some never opened. Thanks in advance.
