Please understand that one of my specialties in silver. I have collected, sold and appraised it for almost 60 years. I have over 100 books on silver.
That said, I have exhausted all my resources in trying to locate marks that look similar to your description. Unfortunately, the marks I am trying to see in your pictures are either too rubbed or too blurred in the images to get a definitive answer to the maker or type of metal.
In cases like this, I must tell you that you will need to test the silver to see if it is sterling or plated silver. You can buy a testing kit at Amazon.com or have your local jeweler test it for you.
I can say that your condiment cruet set is late 19thC or early 20thC. Also, some of the bottles are not original. If you look carefully, you will see these do not march.
This flaw is quite common as the glass bottles are fragile.
Also the quality of the marks has an influence on value.
If your cruet is sterling, it would have an estimated retail value of $900-1400 as is.
If your cruet is plated silver, the estimated retail value of $170-200 as is.
See the following images - both cruets have matching bottles. One is sterling with a reduced retail price of $1320. The plated one has a retail value of $215.
There is a wonderful service in London that makes glass bottles to match. The pricing is not cost effective if you plan to sell your cruet. However, if you plan to keep your cruet, you might consider it. See The Blue Crystal website here: http://www.bluecrystalglass.co.uk/
Yes the name suggests only blue pieces but they make all types of glass.
Online auctions like eBay generally bring wholesale selling prices.
If you would like to sell close to estimated retail, some ideas are:
The internet has your largest audience of buyers. Place small ads on these sites or set up your own small store on these sites.
Be sure to specify local pick up only for large items. That way the buyer would be responsible for obtaining his own insurance and transport.
These sites carry antique as well as vintage items.
Accept PayPal only.
Etsy.com - small fees - 20 cents to list plus 3.5% final price.
These sites are excellent and more upscale but fees are higher. I only recommend them if you have several items to sell.
Or your nearest CraigsList.com where you can list items for free. Accept cash only.
In general, a private seller to a dealer, via consignment or at auction can expect 30-50% of estimated retail value.
Insurance replacement values are usually about 20% more than retail values.
