The four different types of the "F" boxes could only find type 4 in a Superfast box.
The 2 type "F" 1 boxes only have 2 apart from # 39 and # 50 which are also listed as # 1 but have type 3 printing on the bottom of the box.
The 2 type "F" 2 boxes these seem very prolific in the regular wheel "F" boxes.
The 2 type "F" 3 boxes, not too many of these boxes.
The type "F" 4 boxes could only find this type F4 in the Superfast boxes, these were also very prolific in "F" boxes.
Just 4 more type "F"4 boxes not to common to find.
