Tyndale porcelain lamp?

This porcelain table lamp with a water lily leaf and flower motif is one of a pair. It was purchased by my parents in the early 80's in New York. I don't know if new or old at the time. There is a sticker marked with "Tyndale Lamps Chicago" on the lamp holder.

I would like to know its origins in terms of time period and manufacture. Does it have a particular "style"? Is there a Tyndale Lamp company that still exists? This lamp was recently broken. Can I find a replacement or how could it be best restored? I have not been able to find a single lamp online that looks like it. Thanks!
