He is a bona-fide vendor. I have bought an item from him. On my experience can recommend.
I contacted him initially by clicking on his blue text user-name in the advert’ immediately to left and below the accompanying photo’, then in the next screen clicked on the grey text box ‘Private Message’ immediately below the large grey area at the top of that page. That then gives you the ‘message form’. Obviously you do not have to fill in his name on the ‘send to’ line. Subsequent communication was by direct emails between us.
