Help identifying these coconut cups?

I found these recently at a thrift store... they look very similar to the Ed Langbein (MCM Italy) cups or the Taboo Island coconut, but these have a brown outer and upper lip with a older, crackled white glazed interior, thinner walls than the Langbeins and no markings on the bottom at all (which is also more unfinished looking than the above examples).

They are about 4 inches across and 2.5 inches high on average though the edges are varied with a wavy line.

I checked a few tiki site archives and didn't spot an exact match, so I'm guessing they may be cups from a hobbyist mold, possibly - anyone know?

Note also that each cup has identical markings on the bottom (the various dark divots, lines, etc.) and a mold line, so my guess is that they were all probably produced from a mold made from one particular real coconut.

And NO, I'm not asking because I want to flip them. They are currently in home use, and will stay that way. ;)
