Ah ok, if it’s nothing more than trolling I won’t bother poking rich
No, poke him anyway. OP could just be bonkers. Would certainly be enjoyable farce to read about - it would be cheaper and easier to fabricate a new R14 than restore that Regency!!
Even communist Dacia didn't bother to buy the R14 tooling in 1982 when production ended. You could probably buy the lot for £50 even today!
