Need a Screw on cap for 52oz century

[Pamela]

HI,

Thanks to my overly excitable dog my old red lava lamp is in need of a new screw on cap.  I  just joined the forum here in the hopes of finding someone with a spare that they would be willing to part with.  It was originally gold but any color would work better than the paprika spice jar lid and upside down flower pot that is doing the job now.

Thanks.
