Partial Kipps apparatus/gas generator

This is the bottom of a Kipps apparatus. It is about 11 inches high and weighs four pounds. There is a K on the side of it underscored by frosted glass. I've done a lot of research on this just to identify what it is, but I haven't been able to determine age or maker. Because it has the K, I think it was made by the Kipps company and not another manufacturer. I haven't had any luck on Kipps maker's marks. Does anyone have knowledge of lab glass that could help?

I just rinsed it out, so you may see water drops.

Thanks for looking!
