When I become an Aviator

This would be me and my dragon in Temeraire Universe. Yeah I like make commission to myself
I would like to be a Norvegian messenger, going all around the world.

This dragon species will name something like '" Knife- wing". It has simple wing with three lamella fingers. 
So he is a male Norvegian dragon. He is not really tall, smaller than an elephant. Grey and green, with green acid eyes. Short legs, he likes to wear leather and precious metal stuffs.
Not really fast, he has endurence and swift moves. Front of his mouth some thoot come out.

Should find names for them. Any idea ?
