Metal diesel shell company question

Anyone familiar with Ivers Engineering metal diesel shell products? Hardly anything on searches but there must be stuff that I have not found yet. Thanks.

There was some sort of article in the September 1987 Model railroading magazine about an Ivers GE 70 ton diesel kit. Looking in a few places, I found references to this engine, but nothing else in the locomotive line. There are several references to truck and I think car kits (not the railroad variety trucks and cars).
