A sailor for a bond?

It tells me nothing. Perhaps you could give us a bit more of the scene and dialogue?

Mister Micawber, this is the context:

At the Police Station:

Man 1: Sure, they busted up though, just before she moved uptown. Martinez went on the make for Paul Hank. He sent Mary a lot of letters though. She still got them, uh... at least she still had them up to last night.

Chief Detective: How about Mr. Ronnell?

Man 1: Ha!, an out-and-out steal. What a sai

Are you copying a transcript or did you transcribe that yourself from the soundtrack? Could he be saying "What a sucker for a blonde that old baby(?) is!"

I listened the sountrack again and I'm not sure if he says "sailor for a bond" or "sailor for a blonde". The movie doesn't have subtitles. Maybe the second option tells you something... But there aren't sailors in the film, of course. Any idea?

Definitely, he says "sailor for a blonde" It's very clear. No "sucker" here. Could it be american slang of the forties?

I googled the expression and found a song of the Andrew Sisters called "The blonde sailor" and a web page called "sailor and the blonde, blonde jokes and funny stories " but I don't see any relationship with the movie plot.

Well, I can only think it means 'he is a sailor who likes (goes for) blondes'. That's not particularly '40s slang.

I'd better say: "He is like a sailor who goes for blondes". That's because there aren't sailors in the movie, and Mr. Ronnell is a rascal and a gambler, but not a sailor. Ok?

I cannot comment without reading the script or watching the scene.
