ThisRoyd Minstrels. They’re not in best condition aesthetically, but seem to be functional. The tweeters have been replaced and thus the distinctive soft foam anti-diffraction tweeter surround is missing – though this could easily be replaced with a similar material (felt is popular). Similarly although the grills have pulls, the cloth covering can be replaced cheaply (try Winslow Audio). All in all £75 is a good price, these usually sell for £100-150.
