Unfortunately, yes, especially if you use the term "identical
model numbers" loosely, in which case there are often numerous
variants of the same basic model even in the same country.

Seems to me that Panasonic have muddied the waters even more. The seller
of that service manual states on his Ebay page:

"This manual covers all worldwide models!

DMR-HWT130EB DMR-HWT230EB

Pages total: 102"

The manual I downloaded from Elektrotanya has only 60 pages, Both have
the same Order No. on the top right of the cover page (the cover pages
appear identical)! Strange...

IMO the worst offenders are laptop and cellphone manufacturers.
When I wanted to buy a high mid-range laptop for my
architecture-student son a few years ago, it was a real PITA to
choose from, not only different models but also from the numerous
sub-variants of each model with slightly different suffixes. One
Samsung model alone had about twenty variants!!

I wonder if this sort of thing really makes business sense. Do they need
that many variants?
