It was larger in size. I think the legs were longer and the rest was the same, except for the 3/16" launch rod. The asbestos, if present, was a good idea. The blast deflector did not cover the masonite, so even the smaller engines would destroy it in a few launches. The LIA-77 I have does not have the asbestos pad.

The shipping weight was one pound more, 4 pounds for the LIA-100 vs 3 pounds for the LIA-77. I had plans for the LIA-100, but I cannot find them now.
