Original Sharps Rifle Co. Documents

I have an assortment (16 or 17 I do believe) ORIGINAL Sharps Rifle Company documents.  All dated 1870's & 1880's.  Cheques, shop memos, receipts, invoices, postal cards, etc.  Purchased from a collector who acquired them at a gun show in Ohio in the 1970s.  Will entertain serious offers only.  The pictures at descriptions provided are just a sample of what I have, will try to add photos of the whole collection at a later date. Thanks.
