Wider racing rear wheel arches

[427SSSS]

Trevor Legate's book: COBRA The First 40 years, chapter 8 SEVEN LITER POWER page 135 states: ....This example features the wider racing rear wheel arches.

This is all I've been able to find on Cobras with "the wider racing rear wheel arches."

Now, I acquired this Paul Bennett mold, which has a 76" width. I'm wondering if Paul was trying to copy the Cobra in Trevor's book.

Does anyone know anything, or can you send me someplace that will tell me more about "the wider racing rear wheel arches?

Thanks, Wayne
