Netherlands: K.L.M airmail labels 7

Recently came across of this label. Note sure which country it is. But as far i can see small letters "KLM" on the label, i guess it's from Netherlands. Thought it's not listed in catalog.

Year: ?, Gummed. Günter Mair's catalogue no: - NEL-B-?, imperforated, brown-orange/blue/white,
