Years ago I started a thread on a related topic (1982 Rubik's Revenge:Macau vs Hong Kong
) but I neglected to update it with all the relevant information. I will probably go back and add more to it, but here are some findings that are relevant to the tiled Mèffert 4x4.
There were two distinct types of molds, a composite
type in which each component was made of two pieces that were joined after injection molding, and a monolothic
type in which each component emerged directly from the injection mold. Manufacturing started in Macau then Hong Kong, new tooling was introduced in Hong Kong and ultimately spread to Korea. That resulted in four variants of the 1982/1983 Rubik's Revenge:
- Macau cubes with composite parts.
- Hong Kong cubes with composite parts.
- Hong Kong cubes with monolithic parts.
- Korea cubes with monolithic parts.
I had erroneously listed the Korea cube as Taiwan.)
Judging from the distribution of these variants (in 1982 and afterward), the composite
molds were probably rushed into production to fill the anticipated demand for Rubik's Revenge. The monolithic
types were technically superior and simpler to manufacture. The composite
cubes were first to reach the market and dominated early sales, but the market crashed when the monolithic
cubes finally arrived.
So what does this have to do with Mèffert's 4x4, you ask? Internally, the Mèffert tiled 4x4 is made from the same molds as the monolithic
Rubik's Revenge cubes. The mold identifiers are identical, so they were undoubtedly made from the same molds.
So you could repair a Mèffert tiled 4x4 using pieces from a monolithic
1982 Rubik's Revenge.
If you can find one, that is.
But it's not easy to locate such a beast, and it poses a difficult collector-conundrum. If you must use a 1982 Rubik's Revenge to repair your 4x4 you'd naturally prefer to sacrifice a second-hand, previously-used cube. Perhaps a damaged one. But previously-used cubes are mostly the inferior composite
style; they won't fit well, and they'd be prone to breakage. Surviving monolithic
cubes are often MIB or NRFB
specimens, which a typical collector wouldn't want to sacrifice for parts. Taiwan specimens are especially scarce in any form, so their value as a collectible might exceed the value of a repaired Mèffert tiled 4x4.
