Here are some pics of the mortar. As you can see the ignition cartridge is still in tact and the primer not shot. I am still urious as to what the material on the inside is. It is a little less porous than lava like previously stated and more so like an iron ore or omething like an element rock. Also the fuse appears to have been broken off as opposed to unscrewed. Their is what appears to be a rolled iprinted stamp on the body of the mortar but it is unreadable as the body has been painted recently (I believe). Any ideas. And should i be concerned over the material on the inside. Thanks.
