I D These brakes ?

I just finished spiffing up a Raleigh Sprite for the Bike Exchange. Rather than clean up the Raleigh stamped steel side pulls I replaced them with a very shiny set of brakes from the parts bin. The new brakes appear to be almost identical to those on the Sprite. They have a small logo stamped into the face, a curved fish in front of what looks like a stylized rainbow.

Can anyone I.D these brakes for me? they look like they may be forged . They are chromed steel.

I will post some pics of the build soon. I have nicknamed it Sarge. It is very butch.
