A rare 188-page hardback illustrated catalogue, beautifully produced, listing the latest Kollman aircraft instruments of 1949, including altimeters, air speed indicators, sextants, tachometers, clocks,

pressure gages, etc. Each section has a thumb-indexed tab.

The overall condition of the pages is good, but at some point the book was kept in a damp place and there is some discolouration to the cloth cover and a musty smell, with rippling to the first and last few pages.

The photos give a good idea of what to expect.
