In my previous posts, I said that I had a 9" that I had originally gotten from PTC. But I see that they actually have it listed as a 9 1/2".

Lenny had told me that I needed a larger converter to get me where I wanted but that meant the elusive 11" core was needed.

Is it possible that the 9", 9 1/2", and 10" converters being mentioned here are in reality based on the same core?

Master, again and still
