Instructions for Muse
30th Aug. 40 [a]
To BARCh [i].
For September and October LOUISA [LUIZA][ii] should work on the old schedule. Use your special method [SPETsSPOSOB] for reports. Acknowledge receipt of this telegram.
Notes: [a] Repeated on 5th September 1940.
Comments: [i] BARCh: Possibly Simon Davidovich KREMER, whose official post was Secretary to the Soviet Military Attaché in LONDON. He was appointed in 1937 and is thought to have left sometime in 1946. The covername BARCh occurs as a LONDON addressee and a signatory between 3rd March 1940 and 10th October 1940, after which it is superseded by the covername BRION.
[ii] LOUISA: Almost certainly an error by MOSCOW for MUSE [MUZA]. In No. 949 of 27th August 1940 LONDON asked for MUSE's radio schedule for several months and for cipher instructions; this message is on an appropriate date to be MOSCOW's reply. Furthermore, paragraph 3 of LONDON's No. 987 of 6th September 1940 (the day after teh present message was repeated) acknowledges receipt by MUSE "yesterday" of a 30-group message: the present message is 30 cipher groups long. The error can be explained by the similarity between MUZA and LUIZA and Cryillic longhand.
[iii] Special method: the LONDON GRU emergency system ww2dbase
