I'm more inclined to agree with Fortress, a few years back, Walter will probably tell you when, I showed a few pens on the other forum and Walter being also new to the forum commented on the shape of some of my pens (not adversely but constructively). Nevertheless, they went on the for sale group and apart from one they all sold, the one stayed on the display for quite a long time until one day the tourist office sent a customer to me to see me turning and he asked to look at the pens. So I duly pulled out the 'saleable ' pens and showed him. He then asked what was wrong with the pen that I had left in the box (It had a deep waist and was in Mahogany ) In fact I have found the original post picture here. I explained that it was one of the first that I had made that it hadn't sold and so I chose not to offer it anymore!! He then said it was exactly what he wanted for himself and bought it immediately. If you look carefully you will also see that I haven't quite matched the wood to the nib section; the clip must be really tight up to the wood and overall it is a bit of a Bear, BUT it sold and since the customer is always right who am I to argue??
PS Walter didn't like the deep waist but it can't be all that bad; he did after all send me a signed copy of his book!!
Personally I would put all of them on display, choose the best and put them at the front and the less well liked by you at the back and see what sells (obviously don't put up pens with cracks and major flaws but sometimes a minor flaw in wood can be a selling point so long as the brass doesn't show) . However, I would also advise you to have a stock of about 50 because once you start selling, if you run out of stock then you are up the creek without a paddle and you will lose customers.
