Are these 2 pics of a ring clear enough to be accurate, and have I read it correctly as LE453086, does anyone know? Don't want to send in a wrong number!
As far as I can see that looks ok. Blackbirds (like this one) have a ring starting with L (I'm currently using LK+ numbers) and there should be 5 numbers.
I would add that oblique views of a letter or digit can be very misleading as shadows and highlights come into play. In this case, things aren't helped by the ringer having put the ring on 'upside down' making field or photographic re-sightings that much harder.
It is also an advantage (as a ringer) to be able to compare images with rings from the same series, as the relative position of the serial and the address stamps are then apparent. Just to confuse things, I've even seen series (of BTO rings) where different versions of the same numeral have been stamped on the ring - in one case a 6 with a short top (as normally used) mixed with a 6 with a longer curved top used in the final digit position! Once the manufacturer sets up a production run, this can affect up to one hundred thousand rings.
