The Leblanc LL should have an absolutely parallel bore of 14.8mm throughout the top joint.
The lower joint also has the same dimension down to the start of the flare towards the bell tenon.
Be aware that quite a few old instruments have some distortion under the top tenon owing to swelling caused by excessive exposure to moisture over the years, so that to measure accurately requires a bore guage capable of measuring further down into the bore.
The barrels that came with my 1960s instruments had a very slight reverse taper (approx 0.008") ending with 14.8 mm at the lower socket end.
Many other models of Leblanc that passed through my workshop had similar bores. The main change came somewhere into the "L" series (L7 ?)
