			Hi Michael,
I think you are right, it is a Recording King M series guitar made between 1936-1941. I believe the checkered top binding makes it an M-5.  If this is true, the next thing you need to determine is whether it is a 16 or 17 inch body.
I've got a slighly out of date price guide (2005), but they say the 16 inch is valued between $1,000-$1,400 and the 17 inch between $1,400-$1,800.
Here's hoping that the body is 17 inches wide. sb
