Unertl increasing and decreasing eyepieces

Ran across a small box at a garage sale, which had both of these lenses as well as a cross hair cell and three rubber eye cups. Does anyone know how to tell which is which, I am guessing the shorter one is decreasing. Don't have a Unertl scope to compare with. Thanks for any help.

Maybe, if someone would measure the length of a 3/4" Unertl eyepiece lens I could figure it out. The shorter one is 2 1/8", the longer one is 2 5/8". My guess a regular eyepiece should be 2 3/8". Thanks Tom

Both of my Unertls have a 2 3/8" eyepiece.  One a 6x SG&G
the other a 12X 1 1/4" scope.
I would be Very interested in purchasing the eyepieces you picked up.
PM me if you want to sell them.
Thanks

PS,
Was the "small box" labeled "Unertl" or whatever to verify they are Unertl eyepieces?

Thanks, Beltfed. My logic pattern worked out I guess. The box was not a Unertl box. The Unertl was written on a Stith box. There was also a hand written note inside with the same info.
