What can you tell me about this old first-aid kit?

I moved to West Virginia several years ago, and my family moved into this old overgrown worn-out house (my mom enjoys "fixer-uppers") So the previous owner told us the story of this house, that it had been built in the early 1900s (if memory serves, the 30s or 40s), and had been a farm where this woman in her 90s had lived. There was a lot of renovation to do, so as we toured the basement, I looked up to the ceiling and saw this box sitting on to pipes. I got it down and read it. It says on the front "TRADE MARK 'TABLOID' BRAND" and underneath that still on the front it says "FIRST-AID (PAC-KIT). In between it has a sort of 'T' with what looks like a horse inside. On the bottom it says " BURROUGHS WELLCOME & Co. (U.S.A.) INC. NEW YORK,N.Y." and also a U.S. patent number. There is nothing inside so I ume it was all used. Inside there is a ripped paper with the half left saying " TABLOID etc. etc. No. 748 SNAKE-BITE KIT (SUCTION TYPE). It looks to me like it might have been an advertisement for another product of theirs. underneath that it has another paper (both of these are attached to the box by the way) that tells of the contents and what to do in an emergency. The box is very red, full metal and uses metal sort of buckles to close. I know this has dragged on for a long time, but I have found several different kinds of similar items on the internet, but nothing the same, and I wanted you to know what I was looking at clearly. If you can tell me what it is or what it's worth. I would much appreciate it. Thanks.
