About 9 years ago I found a 2 shilling
maroon Kangaroo and map of Australia with inverted watermark.
Swapped it for 2kgs of KGV's on paper and found
2 Australia KGV's 3d blue, perforation comb 14, perfin OS,
with small multiple inverted watermarks.
Plus heaps more finds that I have now forgotten.
The one that is the 2nd best will sell on eBay
