When I looked them up earlier in Overstreet it said that after #1 the Hi-Spot title became Red Ryder (#2 and #3).
Do you have the Hi-Spot issue? I was interested in that one since it has a Pellucidar story in it by E.R. Burroughs with art by his son.
I don't have an Overstreet handy with me at work to check on the numbering but I did get the Hi-Spot #1 book from the LOC - it was a photocopied book. I haven't got around to editing it yet.
I know there is no Red Ryder #2. Did you mean that Hi-Spot #1 was considered Red Ryder #2?
From my memory, there's a Red Ryder #1 with the Hi-Spot imprint, then Red Ryder #3, 4, 5 with Hawley imprint, and then Dell imprint for #6 and on. I've never seen RR #1, and if it's unnumbered, then it may very well have been #2 in the series if that's what you meant? Need to check more into it.
Would love to get my hands on RR #1 and #3 - I am working on #4 and #5 now.
