I have a favorite (somewhat egg-shaped) glass feeder for which I'd like to find a replacement base. The original threaded base was a plastic 4-port. No perches, and not very wide like some bases. This base had 4 upward slanted stems for the ports, where the petals/guards snapped into. I can't find any brand info. I think I may have purchased it at Lowe's a number of years ago. The outside diameter of the threaded glass is 1.3125" (1 and 5/16 inches). I thought of using a single-port stopper, but I prefer a multi-port base. The base doesn't need to be original, so long as it works. I'd prefer a metal base if available and it lasts longer. I'd appreciate any help/advice you can offer.
