Has anyone got a Mullen mouth snaffle?

[Bobbly]

As title, must be 5.25", or any suggestions for newly broken horse, was using an eggbutt peanut link snaffle but she keeps curling tongue up behind the bit and flipping over it so trying a loose ring mullen mouth which she seems to quite like except it's just too big at 5.5", or any other suggestions please?
5.25" bits seem quite hard to come by and 5" just pinches slightly? Thanks

There are several on ebay, new and used.

Cambridge snaffle one of my horses goes best in this very cheap too
