Mr. William F;. Friedman,· · 310 Second street s·E, 

Washington 3 D0:. 

D:ear Bill: 

I received the reprint of your article on Codes And Ciphers a coupi~e of days,ago, and want to thank you warmly for it, and abo~e alr for your generous dedication and for the prominent 

display you ha:-.reeaccorded mym:~chines in the article. I have 

read it with great interest, and I would lli..ka to he~e from you· 

if the reprint can be obtained from the publishers in some 

quantities- I think I could use it with advantage. . ' . 

I suppose that you have now seen Bo. I had a letter fDom him 

the other day~ from Arlington. He gave me a piece of good ·news 

about.you - that your bill has now reached the Presidents desk. 

And I iincerely hope -that.it will not be long now before it 

gets its final signature! 

Our work here progresses, but it always seems so slow to me, 

although it could not be ot~rwise, as our resources in manpower 

are necessarily limited. 

We have now at laat finished' the two prototypes for our 10-rotor 

machine, and they are now on their way· to Paris. I am going there

on Sunday next, a_nd I expect some interesting days.·· · And in Stockholm, my·people there have finished;the production model -- for the pocket machine. I have got some photos of it, and I must 

say that I.i am delighted with it. - It wont be very long, before 

ffo gets a sample~ so you shall be able to·judge for yourself, if 

I am exaggerating now. ~"&\ It has been slow work with the projected portable(machine, the 

reason being lack of draftsmen. But·we have made progress there 

too, and I think that we are very close to the ideal - for our 

purposes·-:.. rotor construction. We also belie.re we ha.ve solved the 

oroblem of the supply of the electric current needed, in a verr 

nea tA..manner. . a.M~ -U..-0~ 

The las.t telecrypto machines,of the type you know,are now leaving 

our shop. And in August or September-we expect to have production 

models for our new telecrypto ready. · And ih the meantime, we have started the manufacture of .the electric drive device for the C- and CX~machines - we have got a very._ 

neat design for it. By the way, it will also be used for the projected portable· rotor machine, when an electric drive for this is 

desired. 

I have now mentione& only part of our activities, but you see already from this that we keep busy. As a matter of fact, I have a 

list of 12 di.f'f'erent devices,-···some of them auxiliaries - which 

are in.different stages of dev~lopment or manufacture, here in

Annie and I are now looking forward to a r~al vacati~n, and we ex- --

pect to leave for Badenweiler on the 22nd, for a stay of 3 weeks. ~ 

In the middle of June we expect to drive up to Sweden for the m; 

summer. We are very happy to get our girts and their families t§·· ·• i 

come to Sweden this summer. - We do hope that both you and Elizabeth -

are well, e.nd we send you 011r 1mrP and bef'.t :re_o:,,1rds. _Affect.iM':l.tely !!
