Vintage OHIO CHEMICAL SURGICAL EQUIPMENT VACUUM GAUGE MEDICAL TOOL INSTRUMENT

Description

Photos show everything. Not sure the age, looks to me to be fairly vintage, however I really do not know. Nice shiny Chrome body, 2.75 inch diameter face. Original glass lens, not cracked. It is a very heavy piece, weighs 1.75 lb. I don't know anything about this, I found one on google, but I did not see the price that it sold for. I can't find any on eBay. In the beautiful condition shown, please use the zoom feature and ask any questions you may have.
