OMG!!! I love the look of the finished model. The weathering is outstanding.
Regarding Revell HO buildings from the 50's and 60's. My Dad built an HO railroad in the late 50's. It had a bunch of Revell buildings, a train station, switch tower, crossing guard tower and farm buildings. Nice stuff. Too bad that they are no longer made.
Go here to see images of the models http://tycotrain.tripod.com/revellhoscaletrainsresource/id8.html
Dig the prices for the models.
