injured pigeon

[pinkychops]

I found a lovely pigeon in my chicken shed on monday evening. It is injured with its leg pulled up. I have an appt with the vet this afternoon, so hopefully she can help him/her. My problem is i very stupidly cut the ring off because his little leg was so swollen and i was worried it would stop the blood flow. I only have part of the ring number which is WHU 2000 and part of a number ending i think is 918? The last 2 digits are definitely 18. Any suggestions to help me reunite it with its owner?
