Long, long before Tower, Horizon Hobby, and all the other major hobby suppliers, there was AHC in NYC owned by Bernie Winston. Likely, the first mail order hobby supplier .Opened in 1931 , it advertised full page ads in magazines like Model Airplane News, Flying Models, RCM Modeler and other magazines everything you needed for the model airplane fraternity- Free Flight , Ukie , R/C plus powered cars, trains and boats. You know, back when everyone built and used silkspan, silk and dope.
Their discounts were excellent and if you were in the hobby during the 40s, 50s, and 60s , that was typically a modeler's first stop.
I remember their engine trade in program. Mail in any old engine , regardless of condition , and you got 25% off a new engine of your choice. Like most kids of the day, I had precious little money and swapping a tired O&R 23 for a new McCoy 35 back in 1964 was an amazing deal. Another time, I raided my coin collection and taped(both sides) Barbary quarters, Mercury dimes and Buffalo nickels to buy a Berkeley Bulp Pup kit. They probably laughed and no doubt made out better), but they were dealing with an 11 year old kid...
Guys who lived in the city made frequent trips to AHC, but it really wasn't a huge place. But every square inch was utilized. One of their employees, Sam Bridges, was an ace combat flyer. I hear that he's in the Chicago area.
In the 80s, AHC sort of lost it's luster. Bernie had passed and the business had a much smaller profile under his son. I just googled them and what came up was a new address- but not sure if they are still in business.
