I don't think of any of the pieces to be brass.
The pieces on the body of the scoop certainly don't, though worn there is no sign of the plating being rubbed away, and seem to be a higher quality design.
The handle seems to be lower quality, and has a different feel and seems to be turning a reddish brown colour where its been worn away.
Perhaps this is an amateur's attempt with some high quality pieces used to decorate it?
