What you are looking for is the globe from the Cheetah lamp which was part of the Safari series. The number on the cap is 15. I picked one up on Craigslist for $15.00 last fall.
I know that you have been "playing" with your lamps....so, make your own. All you need is a red/clear and a yellow/clear and start mixing. The red color is very strong....so use very little of that wax. You are going to want mostly yellow, with very little red. I added too much red to mine, so it is more of a rust-orange than an actual orange, but I will know better next time.
