Lee - if you are looking for true authenticity then you need the older BRCA numbers - somewhere between 93' & now, the BRCA changed the font slightly on the 'BRCA' lettering beneath the number.
I should be able to get you the correct older numbers - but I think the 'register' on them was a little out - i.e the number is a bit low on the circle - PM me your address & I'll see what I can do
