Colt 601 Build

[browningautorifle]

I can't tell how the handle was attached

Any thoughts on how the handle was attached please let me know.

Pics always show a blank butt, like it was flat peened and painted. No sun burst or screw. If you could find a German example there's a phillips screw at the butt and you could slide a handle on, they're available.

Pic of the butt...
