Petcock

Can someone tell me if this was the original petcock. I just bought a Li 150 special. As far as I know the have always been silver in color. As you can see this is brass. Okay can't attach photo due to board attachment quota has been reached. I assume this is the sites server. So I am posting the question anyway. If possible I will post pic when able.
Thanks
