Well, I'm getting geared up for chronicling the adventures of Brian Savage AKA Scalphunter and I thought I would toss in this info from the letters page from Weird Western #39.
I seems that DC made the decision to move Jonah Hex into his own magazine and then cancel Weird Western Tales. However, one of the DC folks heard about this and was appalled. That person was Sergio Aragones. Sergio told Joe Orlando that WWT shouldn't be canceled but Joe replied that they had nothing to put into the book. Sergio replied that they should create something.
Paul Levitz agreed and told Joe & Sergio to come up with something. That something was Scalphunter. They promptly handed the writing chores to Michael Fleisher and the rest is history.
Fleisher scripted the first few issues and then it was handed over to Gerry Conway. Oddly enough, a few of the Conway issues carried a "Created by Michael Fleisher" tag on the splash page. Even the DC wiki had this info wrong, listing Michael Fleisher & Dick Ayers. But, I have corrected it.
