They were required to be demiled to BATF requirements, but the only obvious result of that is a hole neatly machined in the side of the barrel. No demile was required for the baseplate or monopod. This mortar retains a large percentage of its original paint and I think too nice to restore. However, if you choose to do so, I think it could be made to look new. All moving parts are cosmolined and there is no rust or pitting.
All parts are there and everything works.
Although these mortars came into the country without the sights, this one does come with the correct M59 sight housed in the M48 metal carry case with the M42 Instrument Light. This unit is as nice as the mortar itself.
