" This is the smallest of three engines that Weeden made alike. The 155, 156, & 157 were the same except for the size and flywheel. The 155 had a cast lead nickel plated flywheel and the 156 & 157 had cast iron. The engine was made from 1918 to the early 20s with low production numbers which makes this engine fairly rare. It has a cast iron base with a nickel plated brass boiler. It closely resembles a German made engine and appeared much different than most Weeden entries. The 155 is 11"" tall, the 156 is 12"" and the 157 13 1/2"" tall. "
