I found the following Australian A1 overprinted with N.W. Pacific Islands. The 2 1/2 d has watermark 8 (Wide crown, wide A), while the 2 and 3d are watermarked 10 (Narrow crown, narrow A). The 2d looks to have a break at the side line, meaning Die 1. I can't see a break on the 2 1/2, but am unsure of the 3d, which would make it a Die 2. What do the experts think?

Is this a small break on the 3d? Under magnification, I think so.
