Are you guys SURE that #6 is a Ljungman bolt? All the AG42B bolts I've seen have the serial number electro-penciled on them. It might be for a Hakim.
There is a serial number electro penciled onto that bolt however what convinced me was the size of the extractor groove. The Hakim has a very long skinny extractor where as the Ljungman has much shorter one.
Can't see either in the pic, but you are correct.
