This is the second time in 5 years that I found a set of these and lucky us - we found another larger set now listed separately but shown in the last two photos here.
Marked 950 sterling which means that it is at least 925 part out of 1000 pure silver and in this case the 950 means it actually has a higher grade of silver at 950 parts out of 1000.
The sail screws in and can be put into any position you choose while the rudder pulls out to allow you to fill the container with the salt or pepper. The salt has more holes and the pepper, fewer.
Excellent condition. They measure 2 1/4" x 1 5/8".
Please note that the last two photos show this pair along with a slightly different and larger pair that has recently been listed separately.
