Large Cast Iron Garden Urns Planters with putti and goathead FOUNDRY? DATE?

Showing one of a pair here, these measure 48" tall, 30" width … very heavy cast iron garden urns/ planters. I'm not counting on them being "antique" but they are certainly "vintage" … can anyone identify the FOUNDRY which made them? I haven't been able to find a foundry mark, it could be concealed by paint layers or perhaps there just isn't one. If anyone can confirm a DATE when these were made, that would be great to know too. Welcome all comments! THANKS.
