This is three Biggles novels as shown in all of the pictures supplied.  Classic hardcovers with around 180 + pages in each edition.  I am unsure about the publishing date of the Camel Squadron edition.

Used condition books with the cover and pages intact and not loose. Copies are not an X-library copy but do have a removable plastic cover over the dust jacket.  The dust jacket shows some wear around the edges and covers.  Pages are in nicer shape.  There is some second hand book store writing on the inside cover.  Overall this is 3 very solid used condition hardcovers that are ready for another read.

Australian postage is $13.95 to with tracking.

I do combined postage to save on shipping costs, simply request a new total or reach out for help.
