pocket scope for sale, brand-new and used.

This vintage early 1900's Bell & Howell Pocket Comparator , distributed by the National Tool Co. , is in very good condition , although I chose "Seller Refurbished" , as I do clean and inspect every item I post on eBay ! I have taken the liberty of covering the original directions with clear tape , as they are old and now "re-vitalized forever" .
