I greatly appreciate the two of you taking time to respond and I apologize. I should have mentioned I own both volumes you mention, as well as six others on cancels, and I haven't been able to find either of these in any of them. Granted some of them, such as Simpson's book on cancels is for issues prior to this while Cole's deals with Banknote era cancels. I was hoping someone may have cancels like these in their collection, or had seen them somewhere else and could shed some illumination on these two cancels.
So, if anyone has an idea, I'm all ears! (or eyes, as this an on-line forum...)
