cool Vintage old Thomas industries first aid hit compressor. Pat Pend with hard box and original old style labeling, pictures and decals.  Based on the instruction set attached to the box seems very 60s. Cool addition to the trunk of that old car. Item was tested and does work hooking it up to a car battery pump worked as expected. Hose has no dry rot it has plenty of life. And it did pump air. Chuck on it is a tapered chuck not a tire chuck can be changed as required. Only thing to note is I do see electrical tape where wire meets alligator clips AND in 1 other location, I did not inspect it further but it did work just fine as is. 
Please review pictures please let me know of any questions.
