Offered for your consideration is this very rare piece of Soviet ordinance.  These were incendiary munitions for the Soviet 125mm glass ball thrower or the  “Ampulomet”. An obscure and primitive launcher that hurled these balls by means of a 12 guage shotgun shell.

These come expertly deactivated and rendered inert. All retain the the raised ring around the fill hole.  More often than not, this is shattered away by less careful deactivation.  I have a few pieces, all in the same excellent condition.
