Just to prove I'm way too involved in this stuff, these things come in at least two varieties. One is like Marc's with an angle tab on the back (to weld as required to turret rings) and others without but with two holes at the top to accommodate angled mounting brackets for HUW, 2K1 and other soft skin wireless bodies. Some are arc welded and others brazed.
