Unless 100 stockholders of the McCullough Motors Corps, Lehighton, come up with more money to finance the concern, chances are that the industry, which closed on Saturday, will go out of business. Established 18 months ago, the firm had produced 10 lightweight aluminum freight trucks of the 10-wheel pattern. The plant is located in the Mahoning Valley. It is reported that President William L. McCullough and four key men of the plant have left for Lowell, Mass. to seek work.
