Is this the well from the Spumoni's Country Estate?

No.

But, it's highly reminiscent of it.

Back in 1955 ELM published a photo essay in the July issue of Railroad Model Craftsman called Spumoni Country Estate. Over there is one of the featured photos with Ma Spumoni lifting a bucket of water from the well, and Baby Spumoni trying to keep his diaper from falling off.

It's not the same well as in the lead photo, but it may have inspired it.

There's no date on the bottom, so its vintage is a bit hard to figure out. I'm going to take a guess that it was built in the mid to late 1970s based on two flimsy pieces of 'evidence'. And what could be flimsier than some texture paper :-)

The roof is papered with a sheet that looks similar to that used on the 4th version of the Schaefer Brewery, which was built in 1979. The papering on the well's body looks like the same material used on Mr. Pottle's Potworks that was published in the September 1975 issue of Model Railroader - and come to think of it, I think ELM used the same style of roof sheets on the Potworks. So, my guess is that leftover texture papers from a project(s) undertaken in the 1970's were used to make this little model. As I've said before, this is the internet, and this is my contribution to its wild world of flimsy speculation :-)
