Took 2 Years to Find One

Squeeze bottles can readily be found, but Squeeze from Paul's of Muskegon, Michigan took me 2 years to find an intact example. Even our local bottle expert seems to have only one.
It has on the heel its mold-number, then ROOT, then 30-- which means Root Glass Co. made it in 1930.
Perhaps it is a harder bottle as the Depression began in 1929.

I had found almost half of one of these once, one shard an acre or so away from the other- but they fit together. And it took a while to identify the brand from what I had left, but I dun did it. And I was looking for one ever since.
