Is Passe Crassane pear a pear/quince hybrid?

I grew it here and it always seemed like a pear to me. It is french and it is so hard to grow they dont even grow it there much anymore. I grew 2 types of the pear. @mrsg47 would know more but they are sold there in france with the stem dipped in signature red wax. They get fireblight quickly.

I tried it
