There is a set of tables for various tapers on the LittleMachineShop site:

You don't mention the manufacturer of the lathe but if you know the maker you could try here:

6.5 Degrees seems odd.
Good luck,
Findlay.

Looks like a good sized machine.
There is a thread on MadModder forum where a guy is making the spindle adapter. He seems to have had a false start but got there in the end. His second attempt at measuring the taper would seem to support the Jarno taper.

I think he has another couple of threads about his lathe on the forum.
