As Brian says (I seem to be agreeing with you a lot recently
) this is arguably the finest Roundhouse locomotive ever produced.
It cost £2339.16 plus 15% VAT with R/C new.
There is usually a long waiting list for one of these and many regard them as collectors items.
I reckon that in pristine condition as yours is, it's value must be near the new price.
However in this economic climate I don't think people will pay that? It might not be viable selling to US because of shipping and exchange rates.
There are a couple for sale here without description at Sunset Valley RR
but these are a lot less than above.
I'd hate to see it go for less than it's worth. It may just be worth storing it and waiting.
A lesser market would be in the UK but I really can't see anyone in France wanting it, except me
It would be a fantastic crowd puller at exhibitions trundling round with those mesmeric outside cranks and black and silver body. Oh and that whistle....
Alas £2000+ would just finish me off as a happily married person and Cilia would rightly be asking, "has our newly resident barn gnome found a job yet?"
I'm good with chickens though....plucking....
