barbara jackman maybe?

Coloring is off for Barbara Jackman. I am leaning heavily towards Blue Ravine.

It does look like some pictures of Blue Ravine. Some pictures it doesn't look like it, but that could be it looking different in different growing environments. Name doesn't ring a bell, but if I planted it, it was a long time ago.

Paulie?

Don't think so. The petals are all at the same height. Not alternating up and down. Good guess though.

How big are the blooms? Could it be Horn of Plenty?

I would say

Jackamani

Not Jackmani. That is a solid deep purple - no bars - and only 4 tepals.

Horn of Plenty is a pretty decent guess.

Could be horn of plenty. The flower petals on mine bend back, not forward. I'm not sure if that's a reliable determinant. I have not seen any flowers since spring, so might be a type 1.

Not a type 1. Those are almost entirely species and with different type flowers. This is a large flowered hybrid so most probably a type 2. Not all type 2's are rebloomers.
