E-bay is an auction website, so it's possible that you will not get what you want.
Here's another discount sales website for your harmonica search. This is a website that has established prices, no auction.www.amazon.com
look at "musical instrruments," find "harmonicas." Click on harmonicas, and read through the list of harmonica types. Click on "chromatic harmonica," and you are ready to shop.
The prices at Amazon are better than most retail music instrument sellers, internet or at a local musical instrument store.
Knud: thanks for your kind comments, calling me an "expert" on Swan harmonicas.
I highly respect you and your posts, and Fat Jim's replies. You are the real experts at the Harmonica Club.
