Page 5, last stamp and page 9, 3rd stamp certainly qualify as fancy cancels. Unknown to me where they are from. Page 5, stamp 6 has a straightline REGISTERED, used from a number of towns as a cancel. There are a probably a couple of others that are just bad strikes.
If anything, this shows a fair range of cancels possible in c.1930.
In Australia referred to as a "Circuit Book" I buy these at auctions whenever they pop up, lots of "left over" stamps that members have no interest in, but sometimes a rich resource for Postmarks. They generally sell for a pittance.
