Vintage class ring in sterling by Birks

I have tracked down this ring to Orchard Park Secondary School in Stoney Creek (Hamilton), Ontario. The school was founded in the 60s and I think the ring might date back a few decades but you can still find the fantastic red tree crest with the motto Nos metiamur (which I think means "we measure up" or "we rise to the occasion") on the school's website. The ring is size 9-1/4 and marked Birks Sterling. In very good vintage condition, with little wear to the enamel or the band and some patina consistent with age. Cross listed in Men's and Women's markets.
