[donsdetour]

This name O. Reichel is normally associated with military ware in Germany. Came across this item and need more info including a translation if possible.  Maybe a belt case for instrument or camera??

Has a date of 1939 under the name.

Thanks in advance for any info that can be passed to me on this.
