You may want to consider displaying it on the swivel base. I didn't even think of using a TV swivel. I built mine just on a table. But then for display DH made some wooden spinning platform for it to sit on. He then went to JoAnn's and bought green grass style fabric and even covered the base with that. It is way too awesome on the backside to just let it be displayed to not be able to see that stuff.
Now I am so regretting not buying the railroad at $250 as it's close to $700 on
Amazon now that it's retired.
