Using information from The Fisher Stove Story, patents and trademark info I put together some history of Midwest Stoves that made the Old Timer;
William D. Duncan was a pig farmer from southern IL that had his license to build Fisher Stoves revoked due to making his own Fisher adaptation. He went with Cal Cotton (Idaho and NY fabricator) who also had his license revoked due to making cloned Fisher Stoves. They formed Timberline Stoves LTD. 4-22-1977. It appears Duncan went on his own to form Old Timer in March 1978 in his hometown of Mount Vernon IL. (also Joseph I. Beveridge and Bruce S. Hampton on patent) This was called Midwest Stoves Inc.
They patented their own stove that included a Uniflu venting / outlet part that allows a top vent or rear vent with one reversible cover to be flipped over the rear edge for either top or rear outlet. (called the dripless flue collar)
Here is the patent info with inventor names and Midwest Inc. info;
