Model 37 .410 SNAKE GUN made for Jon Olin for Nilo Plantation|Winchester Shotguns|Forum|Winchester Collector

I have a Winchester Model 37 .410 Snake gun That Mr.Olin had Winchester build by his design for his Nilo Plantation in Albany Ga. He had something like 30 of these made. I cannot get an exact number from what ive found out. There is not a whole lot of information period on the gun. The Book THE LEGEND has been the biggest help and all it gave me was about 3 or 4 sentences. Im curious if anyone has any knowledge on this gun or any interest in it.
