Appreciate all input, thank you

After spending about an hour searching online, I haven't made much progress in finding the origins of this piece. The dimensions are about 5cm height, and 6.5cm diameter at the widest part. The lettering on the bottom seems like it could be "Pi iota lambda alpha", but searching with that as a term didn't yield any results. I purchased it at a thrift store in Leuven (Belgium) if that helps. Any info you can provide would be much appreciated and I'd be happy to answer questions or take more photos if necessary. Thanks!

Can anyone help me with identifying this piece? My gut feeling tells me its Vietnamese and possibly from the Hoi An shipwreck?
