Vintage, pocket, medical thermometer.Black metal case w/pocket clip. US Reliable

Description

This is a vintage, medical thermometer in a black, steel case (complete with pocket clip).  Shorter bulb might make is a rectal thermometer...  It reads from 66-160 degrees F.  The tubular, black steel case measures 6-1/2" long x 3/8" in diameter, has a screw-off top (which holds the thermometer).  This top portion also has a loop, in case you want to carry it on a chain, instead of using the pocket clip, which is present.  The glass thermometer is intact, triangular in shape and reads "US Reliable".   I am guessing age at 1950-60's?  The thermometer is about 5" long.
I have tried to describe any issues with this item as much as possible.  I can post additional photos upon request and will try to answer any questions you might have that weren't addressed above.  If you want to purchase more than one item, let me know and I will wait until your purchases are complete, then I will send a single invoice with one shipping charge.
