Long shot: does anyone have reciprocity info for old GAF Versapan? Thanks in advance.

Sorry, I'm still living in the time when all serious lab workers had theri copy of this valuable book.
In my 1977 edition, Versapan is no longer listed. A typical reciprocity chart would be:
Ind.Exp Actual
1 sec 1.2 sec
2 - 2.6
4 - 6.2
8 - 14.5
16- 35
32 - 82
64 - 263

Have fun!
