Vintage cowboys and indians playset/carry case?

Christmas 1971, I got an exceptional and my most favorite toy of all. It was a cowboy and Indian playset that folded up into it's own vinal covered cardbord carry case. The action figures were very similar to the Britian "Swoppets". I could exchange all the little parts and pieces with each other. For instance, I could put and Indians head on a cavalry mans or cowboys body or I could swop thier torso's with each other. The Indians had various head dress's, hair, necklaces and weapons I could swop with each other. All the horses bridles and saddles were removable. The horse's poses were varied and not like the standard "Marx" horses where every horse had the same pose or every horse was the same color. ALL figures were easily removed and reattached to their green plastic bases. The "people" figures were very colorful in that the cowboys plastic was flesh tone and the Indians plastic was of a reddish brown color. The plastic used was of a softer plastic and not rigid. I know that you could purchase this type of toy in various set sizes. For instance, I could purchase 3 or 5 indians on horseback as a set. I could even purchase a set with a canoe. I've searched EVERYWHERE and can't quite find the exact playset like the one I had. It's strange because it's almost like the playset I had was a cross between Marx and Swoppets playset's of the time only better than either. I could open up the case and one side was the Indian village while the other side was the fort. The Indian villiage side was printed onto the surface while I believe the "fort" side actuallhad raised walls that made up the sides of the carry case. I would like to find this playset if I could. Any help you can give me would be most appreciated. Thank You
