I would suggest you post them separately, otherwise there will be mass confusion.

The Holler dagger itself looks correct but the scabbard is not the correct rear single flush mounted type we like to see here, scabbard may have been replaced. Luneschloss looks to have had the generic pommel replaced with an Eickhorn product.. Blade looks very nice too.. a shame. Better, more clear pics would help..Best, Kevin.
