Is there a standard leather that lines the inside of a Kelly?

Is that just for bolide or in general? I thought my 24/24 was lined with swift too

This is just for Bolide. If you read the Bolide section on H.com it also confirms that Bolides are lined with agneau.
I believe Swift 24/24s are lined in Swift, don't know about other leathers.
