Curious about this lamp

I bought this table lamp at an auction in western Pennsylvania in the early 80s . It appears to be cast iron in a dark bronze finish with textured stained glass panels of a variegated orangish hue which casts a warm glow. It became known around our house as the Halloween lamp. I did consider swapping out the glass panels for something more neutral. I paid $30 or $35 which seemed like a fortune at the time. I thought it was a reproduction but I loved that it looked old. I haven't seen others in all these yearsso now I'm curious if it was older or more unique than I had believed. Just curious if anyone has any information.
