Miko: Sorry, I can't help you but I'm sure someone else can.

miko, one side is probably perf 11.5 and the other perf 12. If this is the case, there is nothing unusual about this. Can you pls check and provide perf measurements?

If it's mixed Comb Perf 12 x 11½ and Single Line Perf 11 it's rare

If it's Single Line Perf 11 it's rare
Both are Watermark = Crown over NSW


Perf 12 x 11½
