Here is an 0.833 Portuguese silver jug, pitcher or ewer assayed in Porto 1938-1984.
It is just under 30cm tall, weighs 555g and has a capacity of about 840ml so I believe it is intended for holding a standard bottle of wine.
The maker's mark is recessed in the base so it is difficult to take a good image. The maker's mark contains the letter "E" and is possibly two "_ E" or three "_ _ E" characters long and seems to ressemble "RE" or "RAE". The maker's symbol looks to be a butterfly, dragonfly or similar.
If anyone can provide information on the maker it would be appreciated.
Thanks,
