What type of bitless bridle do i have?

[Joyous70]

I have been rooting through my tack boxes in the garage and came across a bitless bridle that i must have purchased some years ago - but am unsure as to what type it is, it has rings either side of the noseband, and the noseband appears to tighten when the contact is taken up by the reins.

Can anyone tell me what type of bitless bridle it is please

Possibly a Dr Cook?

Scawbrig? A Dr Cook will cross underneath the jaw.

Sounds like a scawbrig to me too.
