Globe Replacement For My Black Squiggle Base with 30R20 Bulb

[Joe]

Hi, all.  I need some help locating the proper globe for my black squiggle base which using a 30R20 bulb.  The base measures 4" across at the top and stands 6 3/4" tall with yellow felt.

Does the globe for this base have a flat bottom or the convex "curved in" bottom?  Any #'s or code on the globe?  I've tried using a flowing convex bottom globe from a 1978 Aristocrat but it doesn't get hot enough to flow in the black squiggle.  If anyone out there has the proper globe would you consider selling it?  An empty globe would be fine as I can replace the lava.

Thank you all for your help and also for the terrific pictures of your Lava Lites.  AWESOME!!

Best regards, Joe
