This IWK manufactured cartridge was probably reworked some time soon after the Second World War. The original headstamp on this military brass case was turned off, leaving a shallow groove. The new headstamp was struck within this groove. Other ammunition manufacturers in Germany, DWM, N (RWS) and DKT also used this method to convert mostly surplus military ammunition, as well as reworked commercial ammunition, into sporting cartridges.
