Excellent find! Notice my avatar - the Marauder was one of my first rockets back in the 80s. I am still getting everything together to make a clone of it. That one looks nice - I would send it up at least once, like I try to do with all of my rockets but that's just me. I do have a couple that probably won't see a launch pad but they haven't been built up yet.

Still, you have a nice little classic there. There is a Marauder in the classic series that is supposed to be introduced next year by Estes, and they said it was based on the #1922 kit, but I don't think it looks much like it at all. All that is my own opinion.......
