Anyone have info regarding older hand operated cast iron water pumps?

[Travis Covington]

here is a picture of a pump similar to what I am talking about..



I am doing a project and require some historical information regarding these types of pumps. So far I have found very little, and thought it couldn't hurt to try here.

I need info such as the original design and manufacturers, what countries used them and are still using them, etc.

This is a project to potentially redesign/retrofit some of these pumps used in third world countries to make them more efficient and easier to use and operate.

If anyone has information that could help me, it would be greatly appreciated.
