Double sided rayon blood chit, approximately 24 x 17.5cm. Printed in red, blue and black ink on two separate pieces of rayon stitched together back to back with a neat stitched edge. For use by British aircrews flying missions over Soviet controlled regions. Printed to the front with a large Union flag plus wording in Russian asking that the holders' details be passed to the British Military Mission in Moscow. The reverse side has a smaller flag and similar information along with detailed instructions for use. This scarce chit comes with the extremely rare plastic acetate pouch/sleeve (approximately 11 x 13cm) designed to hold the blood chit such that the allied flag could easily be seen. This has a black rubberized 'tongue' with a cotton neck tape attached. The pouch could also be attached over a service dress or battledress button. The pouch has yellowed a bit and there is some warping but no loss or damage. The actual chit is superb and could not be upgraded. A vital safety 'pass' for British airmen and a very nice survival item. Stock code E19971.
