Got everything cleaned up. I got 3 Horlick's in 2 different sizes, got a common 1928 Fairfield Farms Dairy Baltimore milk, 2 Free Sample Mellin's jars, a couple lids, a Carter's sca cone, a Waterman's ink well, and a nice light green Helwig & Leitch Baltimore jar.
Congrats Henry on your first of many cones! Here is some trademark info that might give you an idea of what kind of food product would have come in your Hellwig & Leitch jar.
