The first photo is of the Aussie watermarks,this usually determines which Scott number coincides with the stamp,

This is a Scott # 12 1913 typo(Scott # Wmk 8) perf 12 gray and yellow
this is what we call an Aussie first watermark 6
this also has a heavy TPO cancellation but not to bad for the price,



Next is a Scott # 44 1915 (Scott # Wmk 9)perf 12 grey and yellow
this is an Aussie second watermark 7
this does have some short perf's on the bottom


All in all not to shabby
