Just list a piece with photos and describe piece as best as you can.  I LISTED A small pickel fork, cut out handle, floral pattern, small bird on reverse in circle. "The bird looks like a seagull with wings unfolded." Asking, do you know anything about this mark,manufacture or pattern? Would you believe an ebayer  replied with an email "revise and place Norway and "Tele Solv" in title." "Scroll down and download pattern." What did I find but the fork listed in a book the woman was selling on ebay entitled "Norwegian  Sterling Patterns for Brides". It  had the name of the pattern " Tele Solv", firma" (manufacturer) "Broderene Mylius" and date of issue 1924.  It is currently listed under my listings. She added "I don't know current value but you will do very well!"
