New to me Binks airbrush question

Cool deal, thanks! Here's a couple of pics. When I mentioned mint condition, I was truthful.

It says Wren A on one side and Binks on the other

Yes, you did. I think the Binks Wren AB is still available on special order for over $250.00 AB only. The three nozzles are for fine, medium and large openings, they should have 'needles' with them and if unopened probably do. My first airbrush over 45 years ago was a Binks Wren model B. Still have it!! Only problem I can think of is that there is an O ring inside the nozzle housing and after much time may be probably deteriorated but the O rings are available. The Wren is similar to the Paasche Model H or the Badger 350, I think a great AB to start.
