I guess that printafm program, now bundled with ghostscript, was used.
It prints afm for a Type 1 font.
It was written ... by James Clark <address@hidden>.

Thus I have ferreted out of the Net the oldest version of Adobe Symbol
(001.007, attached), instructed my ghostscript to use it for Symbol and
symbolsl.pfa, by adding to Fontmap
/Symbol-Slanted         (symbolsl.pfa) ;
/Symbol                 (symbol7.pfb) ;
When I have run
printafm Symbol-Slanted > symbolsl7.afm
the resulting  file had only minor differences with symbolsl.afm
from groff. That changes may be attributed to changes in Adobe Symbol font
(ver 001.001 vs. 001.007) and (may be) PS implementation used.

Thus the magick stick used to make Symbol-Slanted  seems to be found.

But the problem of the unknown reasons behind changes done by symbol.sed
remains. Can you contact James directly?

            Sincerely, Michail
