Anyone who has the vintage Stanley A-1357B one quart wide mouth from the 1970s and 1980s that either used the non screw beige stopper this works perfect and tight no leaks; a win! This company delivers resonably within a week max and you can get cork replacment for the old Stanleys or even the vintage 1970-1990s one quarts if your missing a stopper you can get a cork one. I so advise you to check this company out. Thanks for being a replacment to the old days of the local hardware store. I just suggest you measure before you order your hole for your thermos.
