Thanks Uni,
 do have another one, bit curious about as well. 1953 1/2d,
 mentions  doubling, but what it doesn't mention is it doubling to the left of it,

Or doubling to the right of it,

or a minor doubling to the right with a diecrack.

Have similar in the 1954's as well.

Also came across this one, top of page 27 in the 1946 1/2d's Dinosaur scales on roos back.
