Hello to all. I appreciate you taking the time to review my posting. I'm helping a friend sell a large number of USGI parts from her father's estate. I came across what appears to be an 03A4 bolt. I didn't want to post it for sale, as such, without verifying its authenticity first. I've read through this forum and others about "tells" to verify an A4 bolt but even so I am still having a hard time coming to a conclusion. I was hoping the discerning expert eyes of the forum members might help me in this endeavor. The link below is to a google photos album that I have created with pictures of the bolt. I tried taking pictures I believe will help with the identification process but if other angles will help please let me know and I can take and upload those photos, as well. Thank you in advance for any assistance that can be provided!!
