Have two SA Bayonets. One dated 1906, SN 119323. Blue finish and never sharpened. Only a partial scabbarb. In a wood scabbard with raw-hide cover laced on back with raw-hide. The other is a SA dated 1917, SN 763468. Also still blue and never sharpened. In canvas scabbard, leather tip, dirty but in good condition. I know nothing about bayonets. Came into these two a few years back kinda by accident. Can anyone enlighten me as to what I have and are they worth the $50.00 I have invested. Thanks in advance.
