Year of patent[edit]

Although the helicopter was designed much earlier, as far as I know, the machine was patented in June 25th 1940, under the patent number 149788. In case there is a previous patent from 1924 it should also be indicated. I've changed the year back to 1940 in the "Patents" section. Espigaymostaza (talk) 22:46, 20 October 2011 (UTC)[reply]
