Kellogg's Baseball Cards - Factory Sets - What Year?

When I find Kellogg's factory sets cheap, I am dumb enough to buy them.  Sometimes I not sure about the year, so my plan is always to pay for it as if it were from 1981 - 1983. 

I have come up with a few nearly fool-proof ways to figure out what the year is of a Kellogg's factory set.

1.  Look for the writing on the box, especially if someone wrote the year on it.  This seems to be an okay approach, especially if the year written is from 1979 to 1983.  If one were going to lie about the year, they wouldn't be likely to write down those years.

2.  Check the label for any information that might be helpful.  I am still looking into how to translate the labels.

3.  Look for color differences in the printing, if there is any.

4.  Check the size of the box since they were not the same each year.  Here is what I know so far about the sizes of the factory sets.  This is by my inexact measuring. 

a.  1983 - 7-1/8 x 4-1/16.  Small, black arrows (SBA) on the package, like the one shown above.
b.  1982 - 7-1/8 x 4-1/16.  SBA.
     1982 - 7-116 x 3-7/8.  SBA, but the package has a pinstripe pattern of two different colors.
c.  1981 - 8-3/16 x 4.  Big, thick arrows on the package.
d.  1980 - 8-15/16 x 4.  Short, thick black (STB) arrows on the package.   I have one of the same size with the big, thin blue arrows, so I am going more by the box size than by the arrows.
e.  1979 - 8-15/16 x 4.  Short red arrows for the thin red lettering print run.  STB for the orange thick card stock print run.  
f.  1978 - 7-7/16 x 3-15/16.  Big, thin blue arrows on the package.

I don't have the mailing boxes for other sets, but here is some other information that I have.

g.  The inner wrapper for a 1975 set, which looks like it must have come in a mailing box like those from at least 1978 - 1983,  is exactly 8 inches by 3 7/8 inches so the outer box must be slightly larger than those numbers.  

h.  The 1976 set came in an envelope that measures 7 x 5.  

i.  7 5/8 by 3 7/8 or 7.5 by 5 for 1973

j.  1977 7 3/8 by 5 yellow like 1978

I was surprised that the 1979 and 1980 factory sets are larger than the 1981 set, which has the largest cards. 

What's up with the two different boxes from 1982.  Has anyone seen this for 1982 or any other year?

I guess I will need to track all of the different style of arrows too. 

Can anyone add to this information?
