FWIW, on the topic of paper tubes, my experience is that the wall thicknesses for all of them are multiples of 0.007 inches, or very close. The tubes tend to be 2 to 7 wraps of paper that thick.
Besides the Estes 3" tube having a wall of 0.035" (5 layers):
o BT-50 is 0.013" (2 layers)
o BT-55 is 0.021" (3 layers)
o LOC 3" is 0.050" (7 layers)
From looking at the data this way, for paper tubes, I conclude you can deduce the number of layers by dividing the wall thickness by 0.007. YMMV.
