LIMOGES ELITE WORKS CHINA FIRST FIRING

Hello, I am so hopeful that this works as I have simply run out of ideas as far as where to turn regarding getting information about the value of a family heirloom.  I am an only son and am in possession of my families (Grandmothers) "Limoges Elite Works China".  I'm told by older family members that it is a first firing and is of some value, but after some exhaustive searching have not been able to verify this.  It is a nearly complete 12 piece setting which includes even a gravy boat, pitcher, tea set, etc.  There is a very unselfish and urgent reason for my request to determine if there is any real value to this set which I will not bother you with, but if you could look at the photos I've attached to see if you think this china might hold some value I would be very grateful, and if there would happen to be any real value to it, if you had any suggestions on who I might contact regarding the sale of the china, that would also be extremely appreciated. Best Regards,John Davis
