Featured Old or modern garden pot ?

Just found this 18" tall by 1/2" (lip thickness) vase, that weighs 15 pounds !
I'm thinkin' it's 99% a big modern garden pot from a local big box store or nursery, but I looked at the primitive base and thought-"Before I drill a hole in this-better check !"
Thanks for any thoughts.

 

Nice size,thick/chunky and heavy. My guess would be fairly new/modern (but that’s just my humble opinion) Personally I still wouldn’t drill hole in it. Let’s hear what the knowledgeable members say..

 

Maybe give the underside a good wash and look for any markings. It also looks like it has a drain hole- maybe covered from the inside?

 

Here's the interior-looks pretty new to me ?...but I'm no expert.

I second that, with emphasis on drilling!

 

I can see the "hole" from both the inside and the outside but something is blocking it. What's the size of the top opening? It looks kinda small and awkward for getting your hands in and planting.
Maybe it's a lamp base...?

Inside:

 

Lamp base, didn't think of that -opening's 3 3/8" across.

 

Garden pottery pot from Southeast Asia. Needs to be "robust" to stand up to weather, etc. JMHO.
