In some part of the universe that has never ever seen a BCA bike in the 58 years I've been traveling this universe. And when I checked for hours on the internet very little was mentioned of the brand. I found 2 people, one said they were cheaply made bikes, and another mentioned they became partners with Ross at some point and made in Allentown PA. I couldn't even find an image of one.

I would therefore conclude that if you have a nice one would be to keep it because it's very rare, more rarer then their cheap ones!! I would also post your images on the web so if others want to see one they can see yours.

By the way the bike I saw was creamish off white color, I can't tell from the photo but yours looks to be almost the same color. Also the one I saw had no decals on the bike except for the head badge, and no water bottle mounts on the frame. Your dropouts are way nicer then the ones I saw. The frame was built by Sakai of Japan with no mention of being double butted so I would assume they weren't.
