Philips 212/312 Turntable phono Cartridge Alignment Tool

This is a Phono Cartridge Alignment tool for a vintage Philips Model 212 or 312 turntable. When this turntable was new back in the 70's and 80's, an alignment tool was supplied with the turntable to get the phono cartridge set up properly. The phono cartridge was installed onto the black sled and the sled was inserted into the alignment tool. The phono stylus was then adjusted to line up at the cross section of the v notch and the front face of the cantilever.
