Specialist auction house for model locomotives?

[davidUK]

Can anyone recommend a good auction house for a lifetime's collection of engines, rolling stock, and books, ideally near Wiltshire (or elsewhere) where they could be assessed?

Many thanks.

Cheffins and Deweatts both have specialist sales for that type of thing and several offices around the country.

That's Dreweatts.

Look for a Bath Model engineering society website... The lads in those clubs are interested and have some idea of what these things are worth.
Check Ebay for similar items? - That gives you a good idea of the market.
