Is it common to find an NSFK with all those stampings on them? I always thought that the DLV Pilots dags had them but not so common on the NSFK ....ordnance and waffenampt also on throat B4 and 250.Ordnance is on x grd and other end the K, incarus winged man on throat . Any real significance to these as far as collectability? Thanks all, Tiep
