[R-390] Special Purpose R-390

[Nick England]

The Clark contract could have been to modify a batch of receivers without regard to whether they were 390 or 390A so the tag seems OK to me. Users often didn't really distinguish between A and non-A. 

I have a vague feeling I have seen reduction dials like that before - but that might be only some self-fulfilling wishful thinking.
