Reichsmarks cast inside a gramophone record that was sent to POW's. Other records contained escape maps. Instructions were issued that upon receipt of a certain type of record it should be broken and the items hidden inside recovered, however in a few cases excited prisoners broke all of the records they had in the hope of finding similar escape aids, but they were somewhat disappointed. Devices such as this one were the product of MI9, whose purposed was to aid POW's in their attempts to escape.
