The phrase "a prototype of such" is correct and usable in written English.
It can be used when referring to an example or model of a particular type or category of something previously mentioned.
Example: "The design team created a prototype of such to test the new features before full production."
Alternatives: "a model of this kind" or "an example of this type".
