Hi Mike, I have been up close to your newly acquired Sipp multiple times over the last 20 years.

It is a 1/2 hp Sipp for certain. It is 23.5" long and has a 1.75" bore X 3" stroke exactly as described in the Sipp Catalog from late 1800s and early 1900s. While your governor and water pump are not original Sipp parts, they are both wonderful examples of period correct hardware that was most likely installed by the original builder. I had located a Sipp with a similar governor some years ago in north east Ohio but the family was not interested in letting it go.

You are to be congratulated on a very fine acquisition!

Gil

ps: If you need a copy of the Sipp catalog, I can e-mail it to you.
