As a Grimbarian ... Born and Bred I have to agree wholeheartedly with Allan when he says the town has declined over the years but on the whole we know how to laugh and smile at ourselves as well as laugh at others.
Grimsby train station would be a great model for you to make Allan and as that would probably only be a short afternoons work for you.
Maybe a model of the town hall /municiple offices and the old Registry office building might keep you busy for an extra couple of hours. ??? Personally i would love to see these replicated in your own unbelievable way..
