Approximately 91! Perfect fuel tanks.  NOS.  Boxes have some wear, most of the boxes I've looked inside, the tanks are mint condition.  Nearly all are 1/2a sizes. 

Tank # and quantity are as follows.

#1 8
#2 3
#4 6
#7 8
#15 9
#16 5
#17 9
#18 12
#19 9
#20 4
#21 3
#22 4
#10 2

Plus 8 loose tanks, and a random Kap Pak tank still in the box. 

I'm thinking $200 shipped for the lot, $2/tank plus postage.

If you right click on the image and "Open in another tab" you can zoom in and see the sizes and descriptions on a lot of the boxes. 

You might try looking them up on Brodak's website.  Add BH-50X and replace the X with the tank number and it looks like the descriptions correspond. 

These are running $12 each from Brodaks!
