Artefacts

Hi, I'm looking for info about a model of the first successful steam-powered boat, the Charlotte Dundas. The original ship was built in 1802 to a design by William Symington of Leadhills/Wanlockhead in Scotland. The model I'm interested in was displayed in Dumfries , but was it at the Crichton Complex or D&G College, and where is it now? There was a three-quarter scale model launched at Falkirk in 1988 but it isn't that one.
