I don't think that is true even if that is what some of the books say. I think Saginaw sent their parts to Grand Rapids to complete carbines. Saginaw wanted to get back to making diesel engines at their plant. They had talks with Ordnance about that. Ordnance looked at both plants as Saginaw and did not care who started making engines or continued making carbines. The IP plant was rented buildings so they could finish up carbine production and move out.
