Does the nick-name of this bomber plane ring any bells for anyone?

`Wanky Wonder' (A Wellington I believe) Snowy Owls 420 Squadron

I've been searching for a friend. His 87 yr old Dad (still living) was the pilot (also flew other planes)

Son wants photo. Dad asked son: `See what you can find out about my old squadron.' (am checking out RCAF sites too...but nothing there yet so thot it wouldn't hurt to try here.

I'd love to help fill the wishes of this pilot especially... his eyes aren't good but his ears and wishes are

Thanks! Carman
