Attached I really do not know our engineers can dope that out so I am sending a set of drawings free hand and these are in detail just exactly like the Russian drawings - so these look a lot better than those I mailed out Sat. and Ubalsty said after I studied them for quite a spell - that he was trusting me - and should I open my mouth or tell any one of the mechanics I saw in them sources I would be taken care of an darn fast - so that's that. When you get these drawings go to the military officials and don't get me in dutch I know you will not for my life is the price I would pay - sooner or later if the commie agents figured I had give this away and do not have any F.B.I. men tagging me that would look suspicions to the commie agents. I am taking a hell of a chance and I want some more information yet from them and I will pass it along to you as fast as I get it
