Name that lamp

[Kim Sallet]

Hi - I picked up this vintage rain lamp, table lamp combo this morning. It's VERY dusty and dirty and needs oil added, but it works! I have searched for hours on Google, eBay, Etsy, and Facebook and can't find one anything like it. It's HUGE - almost 4 feet to the top of the shade - hoping someone here can point me in the right direction. I believe the shade is original to the lamp, but it has condition issues
Thank you for any help:)

I'm not sure what I did wrong, but the photos didn't show up in the post, they are attached.  Maybe it was because I posted from my Ipad?

I bet Steampunk Steele would probably know something about this lamp!

Wow, this looks nice. I think a lamp shade works well with a rain lamp. A bit like the lava and glitter table lamps too.

That's a Johnson Industries model from the 1970s. Johnson models didn't have names. They also made a floor lamp, with a circular glass table mounted just above the rain lamp, and a swag model with three long chains, starting above the lamp, suspending a circular glass table below it.
