White Alto Saxophone Mouthpiece, Brilhart Personaline?

Here's a white or cream colored alto saxophone mouthpiece. There are no brand markings at all, so I'm a bit at a loss for what it is exactly. The profile reminds me of a Brilhart Personaline, but I'm not 100% certain that's what it is.

The mouthpiece plays well. It has the original facing and the tip opening measures .068"

I invite you to try this mouthpiece risk free. Buyers are welcome to return the mouthpiece for a full refund minus shipping if you don't like it for any reason.
