No deep rust and pitting, blade is in mint condition, never sharpened. Lubricant is original German from war period, not cosmoline. Considering the fact bayonet was is battle and wasn't stored and unissued - it has some normal wear and use damage.
This item wasn't reworked - not even wiped with cloth or with fine steel wire. Material seen on blade is not rust. Also material seen on first picture appears to be brass and not rust.
Scabbard discoloration spots can't be felt under finger/nail. Can be wiped out with fine steel wire but I prefer to keep things in their original state. Check 6th picture - frog is missing one rivet - but it is not falling apart. Markings : 6002 C - 42agv.
