Ernie: Been away 3 weeks, but thought I would answer, because, as a scientist,
I am very precise and measure things.
 
A FULL deep averages 70-75 pounds of honey NET
A Full Illinois    "       40-45     "
A Full Shallow           30-35     "
 
New Comb holds more honey because the wax walls are not as thick as old comb.
Depending on how fast the nectar flow was, the comb might be thick or thin
which changes the weight of honey contained.
 
Hope this helps.  Have a nice holiday!                                          George Imirie
