I was planning on entering but have a question I'd like clarified please:  the rules state  "Challenge Certificate winners are not eligible for entry"

Does this include Reserve CC winners?

I've emailed the show sec but I'm not sure the reply quite covered my question, I've emailed the KC and still not received a reply, and I cannot seem to get through to the KC on their general number (constantly engaged!).  Can anyone help please?  Many thanks

Answered now thanks - I managed to get through to the KC        ...finally :)

and what was the answer? just in case anyone else has the same question :-)

The KC confirmed that the ruling regarding entry to a Limited Show is that 'any dog who has won anything which could lead to becoming a champion is not eligible for entry'.   However, under their current system no amount of RCC's will make you a Champion so we aren't excluded from entry.
