Medical desk top reference guide 1962 W.Smith, M.D., old, plastic slide,medicine

This old desk reference for treating simple medical emergencies still applies in today's world......this red plastic desk piece measures 7 x 4 inches......you look on the front and determine what information you are looking for, so say you want to know more about Bites, you would see that that is located under number 4, you slide the ruler to number 4 and push the button and there you have it, all the information you need to know about treating bites......everything is listed alphabetically for ease.....great informative piece....I am an antique junkie.  I do a lot of traveling attending local auctions and estate sales, particulary in my home state and while I try to give as best description as possible when listing items, bear in mind I am not an expert.  That what you see is how it is presented to me. I do not go out of my way to clean up the items; I leave that up to you.  I do no accept returns unless something is grossly misrepresented, so please view all pictures and ask questions.  I will work with you to obtain a mutually agreeable resolution should something like that occur.I ship worldwide and combine shipping as well.  I will ship the same day if you pay for your item before 3:00 PM CDT.  Positive feedback will be given the same day in return.  I certainly appreciate your business and keep me in mind for future treasures.  All delicate items will be bubblewrapped and insured for your protection.  If you have any questions, please contact me.
