18th century England monochords - info.please

Can anyone please point me to or give me information on how John 'Longitude'
Harrison might have used monochord(s)? to pitch train and rehearse an
eighteenth century church choir in Lincolnshire?

One, or many, or multistringed???

We are looking for visual references to use in the Channel Four
feature, which is currently at the casting stage, and wish to make the scenes
as authentic as poss.

TIA
