Bob:
I saw that pseudonym in the same early periodical you did a bit less than a year ago and I had the very same question you did----with zero answer, I'm sorry to say.
I guess Father Simon Carr is a decent possibility because he sure was around prominently way back in that day you're mentioning. Carr was a very good player who won our biggest two tournaments around here back then, and Carr did write at least one pretty significant article about Pine Valley for a golf magazine in 1914 but under his own name.
Along with W.P Smith, Carr seemed to be Crump's best friend at least around Pine Valley and the two of them were recognized by the club to have known more about the details of what Crump was doing and thinking about the course than any others down there.
I'll read through those "Colonel" articles to see if I can pick anything leading up from them.
