Mark,

Went to the link and now I get the picture. Great deal of knowledge on these pages. See that Walter also has a book on the model 37. I do have a 16 gauge model 37 that is a wonderful pheasant gun and grew up with my best hunting partner who shot a 37 in 12 gauge. Always was jealous of him when duck hunting and geese were coming. He could easily remove the shells from his tube and sub heavier loads while I struggled with my 870.
