 The order of the wheels can't be changed.
 So this encryption device doesn't use any key?

Only the most trivial; you choose the row to transmit.

http://www.elcomsoft.com/prs.html#aefsdr :
 
A program to recover (decrypt) files encrypted on NTFS (EFS) partitions
created in Windows 2000, Windows XP and Windows Server 2003. Files are being
decrypted even in a case when the system is not bootable and so you cannot
log on, and/or some encryption keys (private or master) have been tampered.
Besides, decryption is possible even when Windows is protected using SYSKEY.
AEFSDR effectively (and instantly) decrypts the files protected under all
versions of Windows Server 2003 (Standard and Enterprise), Windows XP
(including Service Pack 1) and Windows 2000 (including Service Packs 1, 2, 3
and 4). Registered version costs $99 (personal license) or $199 (business
license).

This is not as serious as I thought.  According to

 It can be easily shown that there is no lossless
 compression method which can effectively compress every possible
 input. 

Even more simply, if such a method existed, you could recursively 
apply it to its output and compress every message as one bit.

The article hedges on whether or not PGP was used on the Psion mentioned.
The Psion might have been using one of the other programs listed at
