Serum bottle - that's interesting.... I know serum = blood....but how were these used back in the day? Some sort of personal use ?....farm animal use? I found his on our property which was homesteaded in the early 1900's - prior to our ownership, only one previous owner - who homesteaded...
I have searched for info about what this bottle might be - it's era - any information on it - it's intended uses etc....couldn't find anything. Can anyone shed some light on this? - any info would be appreciated.
