Chilton Pen Company (made in America), produced quality pens and pencils during the 1920's thru the '30's. Showing here are examples of some of their models. All are mechanical pencils. The far left pencil was sold as a Seth Crocker. Next to it is a Sears. Both were sub-brands of Chilton. Both brands were family names within the company. The company was founded in 1923 by Seth Chilton Crocker. Everybody have a grape day.  😀
