This model saddle, is actually called the,
Mesinger Autocushion.
The hammock type, without the pan, is called the Superba.
Unfortunately, the one on offer here, is missing the identification tag on the back.

Maybe something that Nostalgic Reflections could reproduce with a little research?
There were two sizes of each type.
One for motorcycles, and a smaller version for bicycle use.
This one appears to be the bicycle type, but a measurement to be sure, would be nice.
Also of note, is the broken spring on this example.
My interest, in this, was for possible replication, but I’d have to start out at a reasonably good price, and I can see, that’s not going to happen, so I’m out.
Good luck to the high bidder!
If you do go for replication, 100% accurate, or not at all!
Just my 2 cents.
