Hey there, I believe this to be a M42 German Stahlhelm, hard to tell due to the coating but . For starters leave well alone for now till you know what is currently covering the helmet as there could be German issue decals on underneath the coating.
What is the helmet attached to?
If you do go ahead with cleaning be very very careful as like I said about the decals the helmet may still have original factory paint underneath or possbile camo.
Once cleaned your talking in the area of £100.00-£300.00 (all depending on the paint and possible decals)
