R. Vaughan Williams MS was difficult to read, managed to decipher a bit of it. I noticed he had several he had several places with question marks, where he was unsure of what the singer sang. Need to check those places against the published version.
There are two West Virginia versions in Volume 3 of Michael E. Bush's short volumes. I went ahead and ordered all 5 since the last three are out of print and scarce (individual volumes 3,4,5 are not sold).
The few US versions I don't have I may be able to get from various libraries- which has been working of late.
Now if we can just find the missing English broadside :)
