Take a look at details to enhance trackside and building kits at https://shop.modelstructuresin...ory.sc?categoryId=40
I have a selection of O scale and also HO scale items that I have picked for use my O scale custom structures. As an example items such as standing water tanks make great O scale roof top tanks.
As always there is a 15-20% discount on all items. If you don't see what you are looking for and my dealer carries the product line I can add to my next purchase.
Walther's new industrial tank set attached to a custom DPM building
Rix HO scale elevated water tank and roof top vents on the roof of a boiler house.
Thanks
