Early CJ aftermarket top, I have one that came on my CJ2a. Many of the parts are very similar to mine except I do not have roll down windows, mine just slide up and down. The door over laps the body. There is a pic of the door inside and it follows the tub contour. I don't know the Mfg. but I have not tried looking either. If I had to guess maybe Sears or Wards.
