This is a British reprint and update of a 1953 book, first published in the U.S. It looks like this company re-printed many of the "First Books".

ID. Primary. B&W drawings. UK version of 1963 U.S. 3rd edition. Text revised and rewritten to include more on military missiles, telemetry, planetary probes and launch vehicles.
