German Trip Wire Spool
Well it doesn’t get much more dull than this. This small spool contains the tripwire used to set up the Stockmine 43 and Bouncing Betty mines as booby traps. The wire comes in two colours, desert yellow and temperate green. This one is marked YBW for the manufacturer. These spools are almost identical to those used by the U.S.Army during WW2 and postwar. The difference is in how the spool core is turned and on the code marking.
