Jerry, I have a Sedgley Springfield, #99951 that still has the Springfield markings on the action. There is no serial on the tang, Sedgley stocks are pretty easy to spot, check for the triangle checkering behind the tang, the shape of the comb nose, usually have a schnable forend tip, some good photos in MPs book

I learn something every day, and a lot of times it's that what I learned the day before was wrong
