wooden practice ordenance

[micmacman]

stopped into a indoor flea market today , found a decent flaming bomb 5o cal ammo can to restore $10 , just has a light coat of spray paint , can see the original paint through it

anyway , he had a "WOODEN" practice/dummy bomb that stood about 3 feet , very heavy and actually pretty and n good shape , almost like it had a steel or lead core , that heavy , anyone familiar with these , how collectable , rare , common , what they go for , any info at all?

thanks
