This is a good simple pump but I am not sure how much lift you can get from it.
If you have the time and patients you can make a much improved pump by using a large stainless nipple and leather pump cup in place of the wood only piston he used.
You know those rubber balls you get from vending machines for kids?
A couple of those can make some good check valves.
In the USA you have those Pensilvania Dutch.
Up in Canada we have a few groups of people called Menonites and Hutterites.

I also want to share what I think is about the most fascinating pump ever made the Humphrey pump.
On a wood gasser would really appreciate how clever it is…
Here is a very good read on the subject.
