missing mk4 dsa seat out of XJ494

Trying to find an andy phillips possibly bath ares who removed the pilots seat from XJ494 sea vixen and in good faith promised to restore said seat. We have not heard from him in nearly 4years so if anyone knows anything or notices a mk4 dsa seat on the market please let us know. Seat will either be marked XJ494 left or possibly the old north weald example correctly if im wrong xn650
