But how many of these engines are left, I saw in a previous thread that there was a severe shortage of Bristol Hercules engines with regard to the restoration of the Scottish based Beaufighter, but with all these constant Spitfire/Hurricane restorations are Merlins hard to come by or are they easily reconditioned, do BBMF hold massive spares stocks from internal sources that were never got rid of.
What about German engines, ie the DB for the 109, there can’t be many of these about.
I also notice that restored/new build Yak3/9’s seem to be powered with Alisons, so the massive number of soviet engines produced must have been made back into Zlins or, shudder, Trabants.
