Window

These are now split down by SG category e.g. GA, HC, HD etc. This allows separation of valued from non-valued Window Booklets as there are so many different types.

Window booklets were issued by three printers; Harrison, Questa and Walsall. I will denote these with (H), (Q) and (W) in the title.

Of these printers Walsall by far provide the most variety both in booklet cover and the pane of stamps within. I will be as descriptive as possible when itemising the differences in the booklets.
