Hi, I own a Sentinel Horizon that I bought brand new in 1981ish I want to say. I was told by the Bike shop that I bought it from that they were made in California around the San Francisco area and they had recently gone out of business and the one I bought was one of two that they had left in stock. I had to choose between a red one and a blue one. I choose blue. But they were American made with Shimano parts. Weather they were a subsidiary of Mead I have no idea. But it's been a good bike. I rode it to Virginia when I was 18 in 1983. The freewheeling front sprocket made it much easier to shift while coasting. No problems. I still have it and ride it today
