I have been an old iron enthusiast and a Gas Engine
reader here in Puerto Rico since 2002.

Since I started collecting, I now own six engines of different
models. My friend here on the island owns two Mietz & Weiss hot
tube engines. Many years ago, these engines were used on a coffee

The engines are complete and in “like new” condition. The
flywheel dimensions on the larger engine are 50-7/8 inches in
diameter with a 4-1/2-inch face, and the dimensions on the smaller
engine are 41-7/8 inches in diameter with a 3-inch face.

If you have any information about these engines, or are
interested in purchasing them, please contact my son, Rafael A.
