Searching for Romaine Lettuce D'Iverno a Costa Rossa

I am looking for seeds for this lettuce. I am told it is a Bavicchi exclusive that was almost lost due to weather conditions and failure of seed stock. I am hoping to find that someone has saved seed or still has some seed from a prior purchase. If you know of a source, I would appreciate hearing about it. This is truly a pretty, pretty lettuce!
