If we are discussing general aviation aircraft engines, such as Lycomings and Continentals, there are different magnetos approved for each engine variant. TBO on a magneto is, as far as I know, shorter than TBO on the engine itself, say 500-600 hrs on a magneto compared to 1800-2000 hrs on the engine.
All accessories have a TBO, everything from the vacuum pump to the propeller and it would surprise me if it?s different for a Merlin or any other warbird engine.
I?m not sure that the quoted figures are accurate but I don?t think they are totally wrong. If they are I?m sure that Tom or someone else will correct me!

The refitting of accessories, as You describe it, is news to me. There is a saying though that up north in Sweden where population is less dense you never know what goes on in the woods and maybe that?s how organizations and associations get started!? :-)
