The Agnew Analog Reference Instrument Type 6016 is a fully adjustable scribing platform that will work on any make and model of lathe of any vintage, with a 16", 14", or 12" platter, for 14", 12". 10" or 7" records. Scribing platforms are typically used by mastering engineers, to rest their hand while scribing the catalog number, their signature, or secret messages, in the land around the lead-out groove spiral, without touching the surface of the fragile lacquer master disk. Remember, it is your signature that should be proudly displayed on that master disk, not your fingerprints! Significant quantity discounts available, especially on orders over 100 pieces. Please enquire for details.
