BIG Antique Lot 19 Ledgers Coal Mining Surveys SE Kansas MO 1913-1970 & 1906 RR For Sale

This box of MUSTY hand-written ledgers and paper goods related to coal mining in Kansas & Missouri & Oklahoma was found in defunct warehouse sale in Pittsburg, Kansas. The oldest date I see is 1913 & most recent is 1978. I flipped through them quickly so could be some older. One 1906 book pertains to railroads. Some coal company names are Alston, Wear, Chelsea. Lots of history here for someone who can decipher these numbers! Happy offerding!
