Royal Ironstone China - Warranted Pitcher (Ewer), Basic, Soap Dish with Insert & Vase (?)

Good afternoon, All!

I have six total matching pieces.  I've tried to research this particular pattern and have only found one similar item out on ebay (see LAST pic) posted at $145.  I've seen similar items on 1stdibs for thousands of dollars, but no exact match.  My set is in very good condition.  There is some worn gold spots.

My understanding is that the Johnson Brothers are the manufacturers of this set, made in England in the 19th Century.  Later, the Johnson Bros. joined Wedgewood. 

I came by the set from a friend who received it from her in-laws as a gift.  She explained that it is likely valuable, but she didn't know much more than I've shared here.

Can anyone tell me:

1. Estimated value of the set?

2. Specifics of the two accessory pieces -- is the one, in fact, a soap dish with strainer?  Is the other a vase, holder for shaving soap or ???

 3. Any guidance on the best path to sell the item?

Many thanks!!
