Today I discovered interesting company.
They are called "Miniature Arsenal" and they create scale models (1:2 to 1:5) of various modelguns. They are dummy, of course, but they fully replicate original parts, mechanism, action - they can cycle miniature dummy rounds.
Some very unique models are available, such as Borchard C93, or Caracal F (released as a model even before real gun)
http://www.miniaturearsenal.com/Company was founded when Russian weapons factories started to have problems after fall of Soviet Russia. The first company producing cheap (but high quality) models folded when inflation and amount of work made prices too low to sustain operations. It was later bought up by another private investor and revived as luxury models at high prices. I think there is less than 20 people working there. Making of parts is now done mainly by CMC machines, with manual finish and assembly. Models are made as individual pieces on request, except for the most popular ones that are done in series.
No blowback here, but I think that these can be regarded similar as Japanese ones.
