Hi,
Welcome to the GMB avisk
This is similar to the items from the 'Elwell' find.
For those not in the know, about two years ago one of the Grand daughters of Major Herbert Elwell, wholesaler/retailer of, amongst others, Nazeing glass, sold the remainder of her grandfathers stock. The major part went to the Nazeing Museum of British Domestic Glass, and largely remains in store. Most art glass in this cache was similar to the known and documented Nazeing from pre, and post war times, however it was not as well made, nor was it consistant in sizing, unlike the documented items. It is possible that these were the pieces that were designed by Elwell, but there is no documentary proof of this. These pieces all had snapped off (broken) pontils, whereas known Nazeing, in the main does not.
As a result of the 'find' it is now believed that these pieces are Nazeing, but are not attributable to either to the pre, or post war glass from the the factory's own archive. Therefore, the proposition is that there may have been three periods of Nazeing art glass, the third being the 'Elwell' glass, albeit made by Nazeing. As a result the dateing is unfortunately indeterminant.
