Anyone know what this attachment is for?

Many moons ago, when I still ate meat, I decided to go down the eating "spare bits" of animals route - and make brawn and Pressed tongue.

I'll spare you the details but suffice to say, I only did it once.

^My mum made brawn once. Ridiculous amount of effort for nil reward. Texture - ghastly. Flavour - just as bad.
