Measuring 6 3/8 inches in length. It is a collectible item from the Kriegsmarine Nazi Germany era, specifically related to militaria.
This item likely played a role in naval operations during World War II and would be of interest to collectors and history enthusiasts. The logo is from the earlier time area 1930 to 1938, adding to its historical significance as a piece of maritime memorabilia from that time period. I bought this on an estate sale from a massive German WW2 collection in Scottsdale Arizona.
