I am waiting for the retention certificate to come through shortly but shouldn't be that long. Here's a picture of how it looks, sorry about the few squashed flies!

I'm not looking for silly money on this but it is a good number if you're after an RS04 number.
£799 for the registration plus you will have to take into account the transfer fee which I don't know the cost of these days.
If you are interested then please just drop me a PM.
Thanks for looking.
Graham
