[CAUT] unequal temperament

[rwest1 at unl.edu]

I've been asked to tune an unequal temperament that has been  
described as follows:

There are 4 pure fifths

DFLAT- AFLAT
AFLAT-EFLAT
EFLAT-BFLAT
BFLAT – F

All the other fifths are narrow by -1.6 beats

Does anyone recognize this temperament?  It would be nice to have a  
name for it and find out more information about the rest of the  
temperament from the various temperament web sites devoted to  
temperament descriptions.
