Martin,

There is no easy way to do what you want to do, but I can think of a
slightly laborious way.

Say you rescale a single variable in your estimation by x1000.  The
estimation results won't change except for the coefficient(s) on the
variable, which will also change by a factor of 1000.

If you do this for each of your variables, one by one, you should be
able to deduce what the temporary variables correspond to.

Not exactly an interesting way to spend your time, but it should work.
