Used the set to create a cemetery plot next to an O gauge Plasticville church. Have been looking and thinking about what scale would look right. Never saw any thing ever listed in O gauge anywhere. Saw this set and I thought it just might work. So decided to take a chance. It turned out to be a great decision! 8 have bases. 3 have to be glued. Will glue all 11 for support. Detail on each piece is quite good. This is an example of mixing scales that does work.
