N/A Antique 1920's American‎ Standard Haemacytometer Levy Hausser Counting Chamber

Really cool vintage antique piece! Seems to be in fairly good condition. Don't know if this works and I honestly have no idea what this is. Look at pictures for condition and to see exactly what you'll be getting. This does have an older smell. It's not cigarette smoke, just the smell items get when they've been sitting around for years.
