I don't think they produce this size anymore. The closest you can get from Collins. https://www.collinsdebden.co.uk/Notebooks/Manuscript-Books/Collins-Ideal-Manuscript-Books/297-x-152mm/.

Also check out National Brand, Adams Account Ledger, and Wilson Jones. You should note that these brands (and other brands) offer multiple notebooks with different numbers of columns.
If none of these interest you, try searching for notebooks using the words 'account,' 'bookkeeping,' or 'columnar.'
