This book is the primary support for the volume in Logos 'Marcion - the Gospel of a Wholly Good God' (Fortress Press; ebook in Logos). It's part of the 'New Testament Tools, Studies and Documents v49. Published by Brill (Leiden/Boston), Amazon indicates it's quite inexpensive. It's the result of a Phd dissertation, and is quite detailed with considerable footnotes. Effectively, it's the most that can be demonstrated (ratings solid, probable, possible, etc), that Marcion potentially wrote (from quotes; no writings survived him).
Additionally a sizable number of examples are beneficial in tracing the Matthew/Luke relationship (independent of Marcion).
