vintage brass O ring, 800+ brass plated steel o-rings 3/4'' dia new old stock lot

Huge lot of almost 4 1/2 pounds of brass plated steel o rings... new old stock and in excellent condition. These are open end o rings and are not welded.

Each ring measures about 3/4" across (we measured one at about 0.80" over the outside and 0.63" across the inside), but they are slightly irregular in shape and not perfectly round.

We didn't count all of these rings, but we estimate that there are over 800 rings in this lot.
