BT-55V 16.35" 1.283" 1.325" 0.021"
The one Rich listed is the one I recall.

What are the inconsistencies? Is it the length or the kits listed?
I see now that they have a V listed at 7" from the Vanguard Eagle kit. The classic length is 16.35", which is the K-47 Cherokee-D body tube before being lengthened to a full 18", along with several other K kits.
