Another potential flaw in my memory has come to light today as I was examining the gospel of Luke.
I thought for sure I could remember that once upon a time Logos had the Harmony of the Gospels by Robert L. Thomas and Stanley N. Gundry.
This particular harmony is itself a revision of A.T. Robertson's (which was an extension of John Broadus')
I note that the Cox/Easley Harmony claims to be in the line of Broadus → Robertson as well and it is dated later than my Thomas/Gundry harmony (1988).
At first I thought perhaps Robertsons or Cox might follow the same numbering as Gundry so my question:
Did we once have the Thomas and Gundry Harmony of the Gospels? Or is my memory suspect as usual?
