I have now found It's of a Farmer on the Full English by searching for a list. Luckily, it came up as 3/648. And in a second search it's come up as 2/177, and with the original dots and words too.
I've also found the record of The Bramble Briar collected by Lucy Broadwood in Hertfordshire. But I haven't found either words or dots on the site - it's simply listed as from the Penguin Book of English Folk Songs.
