Dear Rabbi Kornfeld in regard to what you wrote-

>>Another possibility is that when the Beraisa describes the "Guf" of the Chilazon, it is describing the ink which is used to produce its dye, and not its shell (-M. Kornfeld).<<

1. Is this your own chidush or is there a source for this in the mefarshim?

2. I don't understand how this would fit into the word guf, can you please explain.

Thank you

Eliezer Gersten, Beitar Israel
