Is Gemco Ware associated with Westinghouse?

Very often the word 'Westinghouse' is associated with Gemco and this stems from the misinterpretation of the logo on many Gemco items.  The logo is a lower case 'g' with a 'w' above it, and above the 'w' are three dots, giving the appearance of a crown.  This 'gw' logo is found on items from the 1960s right through to the 80s, and they include a broad range of styles, patterns and colours in both clear and opal glass.  There is a theory circulating that items with this marking were produced for a "Westinghouse promotion".  No one actually remembers details of the promotion itself, which is peculiar since it seems to have lasted three decades.

It is very difficult to believe that such a huge chunk of Gemco's production from such a wide time span was dedicated to another company.  Taking into consideration that the items in question are along the lines of cruets, salt & peppers and cream & sugars, the tie-in to Westinghouse appliances is not completely clear. 

In another instance, the Hall China Company certainly made refrigerator dishes exclusively for Westinghouse, and those products were clearly marked as such on the backstamps.  In this case, the relevance of the items and the agreement between the companies are obvious.  If the Gemco products were for Westinghouse, they are definitely not exclusive; the exact same items have been observed with the 'gw' logo and with the ordinary 'Gemco' marking as well.

Realizing that Gemco's full and proper brand name is 'Gemco Ware', it becomes much more credible that the g and w simply stand for Gemco Ware.  The Westinghouse logo has three dots actually on the W, not hovering above it.  No evidence can be found either that Westinghouse owned Gemco Ware at any time, and producing glassware is not an area in which Westinghouse has been involved.  So in the end, the inescapable conclusion must be that Gemco's "Westinghouse promotion" is a myth.
