Nice and clean embossed "The Carbonated Bottling Works Denver Colo". "10" on front heel and WGM buckle mark on base. This dates to 1907-09 or towards the end of their existence. Clean and nice and no staining (just a very small amount of residue inside on the back of bottle but that should come clean with some light scrubbing). This is a nice silver gray color. Very attractive and would go well with your WGM insulators. If you're looking for a nice Hutchinson out of WGM here's a great piece. $75 and that covers postage USPS addresses. PP fine but use the FF option please. Thx. Matt
