The current prices are so sad. Last year we "rescued" a late 1770s brass dial , Selkirk Scotland. Perfect shape but on its way to Goodwill for $400. Didn't even haggle the price since it was for charity. Didn't have room for another big clock but it felt like a puppy to be saved.
You might want to add "Scottish longcase" to the title of your post. There are several members with at least one Scottish clock who might click on your post with more info. And please share more photos. Sue
