Ashton – Chicago Mack 1949 Closed Cab Pumper, #AH20. Hand built in the U.S.A. by Ashton Models. This diecast features many fine details and removable parts. A must have for any Chicago diecast collector. All Ashton Models are retired and were hand built in very small quantities. Our Ashton stock all come with the original packaging. Some may have been store display models kept under glass and away from natural light. Others have never been removed from their original box. 1:43 scale.
