1918 Fichtel & Sachs Butcher blade Bayonet With something macabre and unique.

Hi,New to the Forum,I recently purchased a 1916 Fichtel and sachs Butcher Bayonet and scabbard at a yard sale near me.This came with a story of the history of how family came into possession of it .It has been with family since 1918 when it was captured,along with Mauser,which unfortunately,at some point,was stolen.This had been hidden in rafters of house for 50 years since 1918.Once retrieved,passed down to different generations.People I purchased from,had no interest in it,and were put off by the macabre element of it,That being,IT HAS 1916-1918 blood on it. If pictures loaded correctly,I have tried showing this.Not sure if blood has helped preserve it,but it is in my opinion,in incredible condition for age.My questions are... What would be approximate value? The blood has no significance to me,it is part of that family's story,Should I clean it?
It in very good condition,handle wood nice,scabbard has some small dings.Thanks for any help or info you can offer.View attachment 18View attachment 180705View attachment 1807060704[/ATTACH]View attachment 180705View attachment 180706

S98/05nA Sawback removed, started as sawback piece for Bayern army, proofed 1916, in 1917 was sawback removed, the coat is a oil/vaseline coat of blade that dryed out in years, when there would be blood so it would totally rusted as blood is salt solution. b.r.Andy
Yes it should be cleaned with alcohol solution and reoil the metall surface, as finger prints could made longtime etchings.

Re My question.

Thanks for answering,I appreciate it. Kind of relieved about the blood thing.Guessing the family was going by what was passed down through the years.Cleaned and oiled,What would approximate value be? As I purchased to resell,Not a collector.Where would be appropriate place to sell?

at prices look at Ebay probably, or here in trader? b.r.Andy
