Diamond with 784 mark

[davidbg63]

This is another I'm curious about. About 6" in height and 2 1/2" across the base. Slight purple tint, only marking is the numbers 784 inside of a diamond and also looks to be a #2 possibly mold number. Any Ideas as to the manufacture or contents.

Diamond with 2-, 3- or 4-digit number inside………Illinois Glass Company, Alton, IL (1873-1929). (Numbers found within a diamond on several types of bottles have been matched with catalog numbers found in Illinois Glass Co. bottle catalogs.) Exact period when this type of mark was used is uncertain, but probably sometime in the 1910-1920s period.

Other companies that might have produced some of the bottles found with these basemarks include Diamond/Dominion Glass Company, Montreal, Quebec, Canada & other locations (later Domglas); and the Diamond Glass Company, Royersford, PA (1885-1990)

Looks like a small food jar, possible for relishes or condiments to me...
