This person on state this is from ARNOLD . Arnold HN2197 Diesel Locomotive 1608 Renfe Silver and Green Livery New | eBay 1- 2- I say No way,it's this Ibertren (Spain) Alco DL500-C and not from ARNOLD. Tom
http://www.hornbyinternational.com/...otive-1818-renfe-silver-and-green-livery.html Here is the N-scale version on Hornby's website. Hornby has owned the Arnold brand for some time and has produced many European prototype under the Arnold the brand. I believe this is one of the newer models.
It's Arnold (Hornby) all right. Ibertren made a model of the same prototype once, but it's pretty crude. If Arnold made their model painted for OSE (Greek National Railway) I'd snap one up, but they haven't George.
