Beta Wanted: British preferred

[cygnavamp]

Hi! I'm planning on writing a Gargoyles fic where the characters find a diary written by a female gargoyle who lived at Knight's Spur in the Victorian Era. I'm usually pretty confident about my spelling and grammar, but I want the diary entries to have British spelling. Colour, honour, practise, centre...you get the idea. So, could someone help this Yank write like a Brit? Any hints on the era may be helpful, though gargoyle mores are fairly constant no matter the century.

Thanks!
