Hello Frank,
Welz numbers the illustrations of Lawrence Twentyman’s marks from 131 to 149 in his book. The mark on your piece is 138. If these are chronological then this marks comes around the middle of his time working in the Cape. However, I suspect that this is not the case and they are randomly listed. There does seem to be some kind of “date letter” system but only going from A to E in both upper and lower case, with one example of an upper case R. The letters do not run alphabetically with Welz’s listing numbers. The only other dating clue is that the marks listed from 131 to 134 include a fifth mark of a bird.
If ever I find another copy of Welz’s book I will post in the “Books for Sale” section. Don’t hold your breath though!
Paul.
