Need some help in identifying a bottle.

[Niagara Dry]

I've got this old newspaper advertisement scan from 1930 showing off two bottles from Springwater Bottling Works of Niagara Falls, Ontario. One bottle (on the right) is quite obviously a Niagara Dry Ginger Ale bottle, but the bottle on the left...I can't quite make out the name of it along the top of the bottom label. My best guess is maybe "Colonial" but I'm not 100% certain.

Any help in figuring out what it is would be greatly appreciated.

Update: my father solved it, I believe. Apparently years ago he had one of those bottles, but didn't know it was Springwater Bottling Works. According to him, it's likely "Gold Seal Ginger Ale".
