Bridging sequences from the Bugs Bunny Show

Apologies to bump an old thread, but does anyone have any idea on where I might try to find some more of these missing bridging sequences?

I've been trying recently to find some, and no matter where I look, everywhere seems to be a dead end.

I messaged GoldenAgeCartoons, and heard nothing back.
I tried to contact the 'That's Not All Folks' group mentioned above twice, but neither attempt was accepted.
I've trawled through forums, but all I can see is people talking about how someone else found it, and it usually leads back to a dead link.

I'm ideally hoping to be able to track down Season 2 Episode 15 (Is This A Life?) and Season 3 Episode 24's bridging sequences, but it doesn't seem like any of the sources I'm finding are accessible.

Any ideas would be much appreciated!
