Connor - this is a timely question. Next weekend is 'Apple Day' , with
events up and down the country. Many of them include an
apple-identification service.

Check out http://www.commonground.org.uk/appleday.html for info and
click the "Events" link to see what's in your area. We went to the RHS
one at Wisley a couple of years ago, and found it really interesting. I
may be wrong, but I don't think they charge for their apple id service.
Not during their Apple Day weekend, anyway.
