Members, please help me to find some reference books that cover the Model 37, specifically the 410.

And, does anyone have information on the variations of forearm and butt stocks for the 37-410.  I know that there were at least two forearms, but not sure which is correct for which era.  The Red Letter version wood seems to be different from the later ones.  Of course, there were other item variations, such as the top lever and barrel roll.  Any hints would be wonderful!  thanks, Elliot
