I have used this paper (VC) and had some very good results. My notes are- that it must be used with a red safelight, that it is a little slower than modern style papers, that it must be developed to completion - 3 or more minutes as unlike some modern papers, it has no incorporated "developers", that it is soft by nature, negatives that are taylored to pd/pd print very nicely on this silver paper, that it responds well to split grade printing, that at one time I suspected it was the same as ADOX Vario Classic (no longer, another fine paper, perhaps my favorite) and that it gives me the very best blacks with a few minutes in KRST, and they are very black indeed...
Here is some pudding...
