Erwin,
I do not know if the Alsthom was built under licence. I think not.
As far as the model is concerned it is mainly Nickel Silver and not white metal. I give you some more shots of construction.
The Nickel Silver body, folded and soldered, sits on top of a Nickel Silver chassis which takes a Bachmann motor and flywheels.
The original plastic bogies have a metal overlay and resin sandboxes
The roof is contoured in resin, with the metal parts snuggle within.
Buffer height detail.
There are more photos if you need more detail.
