I have been looking for connections regarding the names in the song, I noted that someone suggested that Blobbs was a reference to
L.C.Dunsterville, I can find him referred to as "Stalky" but not Blobbs. I did however discover a reference to Kipling as "Blobs," from the three black blobs of his eyebrows and moustache.
Kipling was in SA during the war.

I do not know the answer to this, I just thought it may be interesting.
