Looks like a very nice stock. As stated production run for Std Pro.Type one;I cut highwood.
Type two; oval cut highwood. type three; same oval cut, low wood. As stated most type two have been cut to low wood configuration. Depending on where modifications and upgrades are done depends on who marked them or if marked at all. Or all external markes on stock have been sanded off . I hope this helps. And I hope you get them preforming as they should.GK
