What angle is the 'tab' that holds the screw at? As I recall, the 'parallel' tabs (i.e. everything makes a nice line on the back of the head) were Gotoh SG36..
On the US made pointys, most common were the non-logo Gotoh SG36 tuners. Occasionally you will find Gotoh tuners with the logo, and occasionally they used Grover tuners.
