It's been a while since I worked with those - probably 7-8 years now.... I don't have any of the extractors left but I recall a slight difference in those if you place 'em side by side..
The S/N to note is 119,000... I originally obtained 'em from Gunpatch Parts Depot - and the part number for those above that S/N is #6300.. For 119,000 and below, it's part #1200..
Did Jack First ask you for the S/N of the rifle when you called?
