I don't recall what I had used, maybe a set of the Cragars out of the Landy Dart. If I remember, when the Drag-On Lady kit came out, mine had the Cragars in it I believe but then I bought another one later and it had the Cragar/Keystone things in it. Not sure why it would have changed but if you look at ModelRoundup kit listing it shows what appears to be a Cragar mag on the boxtop which I believe mine had.
