What I know about it retains 98% of its original anodized finish throughout and it shows only very modest handling wear. The pistol also features all matching serial numbers.
The pistol was arsenal re-finished/re-worked in 1920 where the barrel was shortened to its current length. The gun was originally unit-marked on the inside grip area, but these markings were X-ed out during the arsenal refurbishment and are now illegible.
This weapon has a sear safety. I assume that the original mag was damaged and/or lost to time and that a replacement mag was inserted and serial-numbered at the time of the arsenal refurbishment to match the gun.
Unfortunately no other accessories, holster, extra magazine. Just the pistol. Hope that helps
