Sal, thanks for asking. Its a fair question and I'm glad you asked it. It made me examine why I thought that I was right.

Here are a few links that support my assertion:

There's no doubt that Komamura makes Horseman products or that Komamura sold LF Topcor lenses, see the Horseman catalog on cameraeccentric. That Komamura sold LF Topcor lenses proves nothing.

The sources I cited are pretty shaky, so I think I was mistaken.

Thanks again for making me reconsider my position,
