According to master lure maker Gary Eoff this is a one off Big Dog. It is clearly vintage, probably from the 1990's and made with hand cut abalone shell.
It was clearly someone's go to lure as it has bill rash, bite marks and a few notable chips on the nose.
It's the vintage Marlin Magic you run, not put on your shelf!

All Marlin Magic Lures are hand-made and individually crafted. Gary works on every lure and he and Marlin are always developing new models and shapes.

Some of the most notable shapes include the Ahi P, Ruckus, the Pear family and Smokey Joe. All the lures are tested, fine-tuned and perfected by Marlin before being released.
