Does anyone know where I can get a replacement 32A MCB for a MK Sentry
(circa 1975?) - local wholesaler says they are rarer that rocking horse
s..t, and suggests that I replace the entire consumer unit!! Not impressed.

MK do a kit for mounting up to 3 current MCB's into an older
Sentry CU (they say suitable for non-'s' suffix and non-'K'
prefix CU's). Part number is 5567s. If you want to fit more
than 3, then you also need a replacement busbar, part 5511s.
