Re: Got Sh-1 59 but doesnt fit my guitar i think LOL
On my steel rule, the end-to-end gap across a Gibson/HPI humbucker surround measures 70mm.
An EMG humbucker measures 68.5mm at the top and 70.5mm at the bottom.
The neck position pickup surround illustrated in your photographs appears to have a gap of 68mm. i.e. A snug fit on an EMG humbucker.
On the first three open bobbins Seymour Duncan G-spacing humbuckers that came to hand, the end-to-end measurement (allowing for the rolled edge of the bobbin) is 66mm.
By my reckoning, a genuine Seymour Duncan SH-1B or N '59 humbucker should mount in your "EMG" surround.
Looking at your photographs of the underside of the pickup, the typeface used for the model ID sticker is not one normally used by Seymour Duncan.
