This candy contaner is listed in "Collector's Guide to Candy Containers" by Douglas M. Dezso, J. Leon Poirier, and Rose D. Poirier (1998) as being circa 1918-1923.
It has the following mark embossed in the glass:
"Westmoreland
Grapeville, PA
_ _ _ N or H NO286
PAT APLd FOR"
On the 3rd line, there are three characters not visible, the fourth character is either an N or an H. We suppose that the number 286 is mold or item number. The metal roof slides on and off.
