Thanks Partime.
I find it interesting that Scott says the Australian Post Office used less-than-perfect sheets which had been pulled from circulation for use as their perfin stock.
I don't have the capability, right now, to supply a scan of the lot I bought; but hopefully, you should be able to see it here:
http://www.ebay.ca/itm/331390485989...m1497.l2649.All (except maybe the 5 Shilling) are common and low CV stamps.
I've identified the Perfins as
114,114a,142, 143, 221, 223,224, and 225.
Any help is appreciated.
