There are lots of empirical difficulties for the UK economy, particularly
in guesstimating hours worked. And productive and unproductive labour are
problems too. And continuities and breaks in the series, and lots of other
problems. But for what it's worth, my provisional estimates for the UK
economy are as follows:

Assume all labour is productive. Then the value of money falls from 5.0992
in 1948 to 0.0835 in 1996. Taking the inverses for the MELT, an average
worker produced 0.1961 sterling pounds per hour of value in 1948, and 11.97
sterling pounds per hour of value in 1996.

Assume only some labour is productive (C-P-C' is productive; C'-M-C is
unproductive in terms of circuit of capital). Then the value of money falls
from 2.7909 in 1948 to 0.0239 in 1996. Taking the inverses for the MELT, an
average worker produced 0.358 sterling pounds per hour of value in 1948,
and 41.81 sterling pounds per hour of value in 1996.

There are lots of empirical problems, and one needs a feel for plausible
orders of magnitude. But ex post it's certainly possible to calculate time
series of the value of money and its inverse. One might not have a theory
of determination, but at least rough accounting measures are possible (ven
if they still need more work!)
