Ill let you know what you're in for. This isn't a chain, its a small crowded store that looks like it came from the early 80s. He caters to an absolutely HUGE Rail market in Columbia. And that's over half the store! They have their club at 1800 Lincoln St. Its called AMROC Associated Model Railroads of Columbia. They are open to the public any Thursday evening, though do look them up. THAT place is unbelievable.
New Brookland carries Tamiya paints and others plus has a TON of just boxes stacked on one side. They used to carry a good selection of styrene sheets and brass tube ect, though i wasn't looking at that yesterday. And the old man that runs it is just great.
Minimal Sci Fi, no Bandai or games, though I was impressed yesterday on some of the big kits he had in stock, ships, armor, and some props. He does buy and trade and had a selection of older 72 scale Hasegawa and Tamiya etc planes that looked like they came from a collection.
Its almost like a time capsule, and I hadn't been there in years myself.
