Thus, check your engine number. Also, you didn't say what your
TR6 _did_ have! My '70 has both vacuum advance _and_ vacuum retard. It's a
real pain, since that means it doesn't have the timing adjuster, so all
adjustments must be done by moving the distributer. If your engine number
indicates a bastard configuration, with the book you might be able to persuade
them it's correct.
It's also quite possible someone replaced the distributer with one
from a parts car at some point.

To the best of my knowledge, no TR6 ever came with a Delco distributer.
Perhaps a GT6 did, though that would certainly be unusual. Sounds like someone
did a transplant.
