Ertl, later joined the ranks of toy truck producers. Aside from Buddy-L, Marx, Structo, and Wyandotte, who had previously made toys, most of these companies started moving into toy manufacturing immediately after the war. 1940s to 1950s In the late-1940s and early-1950s, Nylint remained committed to wind-up toys and soon produced a front-end loader wind-up which resembled a forklift. They then designed and built a couple of motorcycle tin wind-ups, a street sweeper wind-up (resembling an Elgin machine) and a wind-up that resembled a popular TV icon -- Howdy Doody—although Nylint never used the name to advertise the toy. The Elgin Street Sweeper demonstrated the success of toys patterned after real-life vehicles. In 1951 Nylint started to make high-quality construction toys that were patterned after real construction machinery. The first construction toy was patterned after the Tournarocker made by the R.G. LeTourneau Company. While it was high-quality, it did not have the high price of toys made by Smith-Miller and Doepke. Smith-Miller and Doepke, because of increased competition, were soon forced out of business. Nylint also introduced a second heavy construction toy in 1951, a large high-quality road grader. This toy, while realistic, wasn't patterned after any specific manufacturer's grader, although it did resemble an Adams grader of the day. Through the mid-1960s, Nylint produced toys patterned after manufacturers such as LeTourneau (now part of Cameron International), the J.D. Adams & Company of Indianapolis, the Frank G. Hough Company of Libertyville, Illinois, the Pettibone-Mulliken Corp. of Chicago, the Austin-Western Works of Aurora, Illinois, and the Clark Equipment Company of Benton Harbor, Michigan. Nylint made their toys as realistic as possible, and they gave credit to the real-life manufacturers. By the early-1950s, demand for quality toys was paramount as the first wave of post-war baby boomer boys (and girls) were hitting the ages of four to eight. Disposable income was high, and the demand for pressed-steel trucks and other toys was at an all-time high. For several years in the early to mid-1950s, Nylint made construction pieces exclusively. In 1956, Nylint started to take advantage of the Cold War military craze. They made several missile-launching gun toys and made an uncharacteristic plastic ballistic missile set. These military toys had many operating features and sold well. Nylint also made a couple of battery-operated toys in this period including a modified version of the Elgin Street sweeper and a military Electronic Cannon truck.
