Nice Sykes Heavy Wall Fask
This piece appears similar to 213 on page 277 of "The Powder Flask Book" by Ray Riling. 6" overall length, marked Sykes patent shows the Sykes 3 notch spout 2 1/2 to 3 1/4 measurements . This was probably a flask for use with a recession rifle. Heavy wall flask not intended to have a leather cover. Spring works but may be a very old replacement. A piece for the collect or for use. Has not been cleaned or polished.
