New old Plasticville

[baltimoretrainworks]

Are the current issues of Plasticville O/S using the old molds? If so how about coming out with some of the harder ones to find like the Cattle Pens, Grandstand and its associated brethren or the Storybook structures or have the molds seen better days?
as a side note, anyone know why the HO coaling tower and the O tower differ so much? I like the looks of the HO one better.
