It's getting quite common with older devices that scams like this are happening.

It's not only old devices, and it's not just EBay. As a member of the AES Standards Committee and several working groups, I've long had contact with engineers from major manufacturers of connectors and audio components. Quality connector and microphone companies like Neutrik, Switchcraft, Shure, and Neumann have long been plagued with wide availability of imitations of their hottest products for sale at low prices.

In addition to the unfair competition and violation of patents and/or trademarks, the imitations are often imperfect in important ways -- mics with poor response, and connectors that don't physically fit together, or with dielectrics that melt upon soldering, or with poor contact materials.

Far afield from electronics, there have long been problems with fake hardware of all sorts, including structural connectors that hold bridges and airplanes together. The completion of a major highway bridge near San Francisco was delayed by more than a year by exactly this sort of issue, and the added costs were huge.
