I believe that it would be better to measure the total length of the
clarinet not just the combined length of the two large joints. Barrel
lengths are not necessarily consistent from manufacturer to manufacturer or
from era to era. For example, I have a Pruefer clarinet and a Leblanc
clarinet. Both are Bb instruments. The overall length is the same but if
you take just the upper and lower joints, the Pruefer is shorter. The key
holes do line up but the Pruefer has less length above the register key.
This length is made up in the barrel.

Also pitch of an instrument is not only a function of length but of the
length/diameter ratio. I've seen a formula for this but I don't happen to
have it.
