Now I need to find some way of getting a good sale instead of constantly using ebay which as you know is difficult.
We sell on Rubylane.com and get pretty good results (not meant as an advertisement for us but rather a general recommendation). They have a flat fee structure, rather than taking a percentage. Most of their shops are American, but there are a fair number of UK dealers as well.
I know some people have had luck with selling vintage items on Etsy.com, but I've never tried it.
