@Bullo - try looking on a Euro based EBay. There are a couple on a US Ebay listing but the price is high! One was selling for 49.99 US$ and another was selling for 59.99$ and that's BEFORE shipping which is ~27 US$ to Switzerland! Make sure you get the MILITARY version though. THe Italeri Civilian version is available for a lot less but it's not nearly as nice looking.
Well it was, but it was a big wooden box, exposing on 4 x 6 glass plates, and used magnesium powder as flash !
Loris, have a look at King Kit web site - they may have a Ju86.
