I live in New York. We had Hi-V and Low-V subway cars on the IRT Subway. I have seen 1 or 2 photos of what I believe were the original Market Frankford cars. To me they look extremely similar to the IRT cars. Any delails as to who manufactured them and any additional photos. The photos that I remember seeing were photos of them looping at 69th Street.
