Post Update 5/29/16
Dennis Gundersen of Grace and Truth Books sent me a message he said I could post here:
Thank you, Keith, for mentioning us. Yes, Dr. Belcher has reached the age of 82 and asked us to take over the storage and distribution of all his books. So, in addition to the 31 volumes of his "Journey" series (starting with "A Journey in Grace", shown above) we also have his biography of A. W. Pink, his two collections of the Letters of Pink, and various books on preaching, the Sabbath, and biblical exposition.
As Keith suggests, for anyone unfamiliar with these, the first set is a fine place to start.
