my thingy arrived. 260 grams, 19 in. long (48 cm.)looks like it used to be longer as there is a more recentfresh cut right at the end, wich also has a broken off steel pin in the centre, like the remains of a hook or eye used to hang it for display. i think it may have been cut to fit luggage.
anyway, sems to be a thrower more than an exercise thing.
