12 in. German Stein Circa 1870's. Family heirloom.

My family brought this stein to America from Germany in 1879. I have translated the verse already. The stein is 12"tall with lid closed. There is a 777 painted near bottom of handle. On the bottom is written, Germany, a drawing of a triangle,and 10G. Also, e,kol (that is a guess). 901/19590

This was just given to me by my elderly uncle. I would love any info!
