I (for some reason) collect old ligatures! Over the years I have obtained 4 of these eddie daniels ligatures. They feature two metal plates on the bottom, and several plastic "ribs" around the inside of the ligature. One of them for some reason has a different type of leather, shown below:
There was a generation before this however.
From this thread I gather there was a model where the plastic "ribs" were actually rubber.
This would be so nice because the plastic ribs cause slipping!
Does anyone by any chance have any leads on where to obtain such an item? I know it's pretty obscure but I thought I'd try asking.
