Can anyone identify this pre-1960's western?

Hello,
Can anyone name the film which had the following scene in it?
It is a techniclor western, possibly 1940's.
The scene I can remember is a man enters a saloon, looking for someone. A drunken indian is sitting slumped at a table with a blanket covering his head. When the man leaves the saloon, the 'indian' turns out not to be an indian, but the person who the man entering the saloon was looking for.
- I know this is a difficult one, but there might be a western expert out there who can identify the film.

Cheers.

I don't know, I'm not an expert on 40's films, I'm more into the 60's and 70's when it comes to westerns. But maybe someone else here can help. Anyway, welcome to the forum!
