I would like to trade a mint Sinn 356 Flieger (with bracelet and leather strap with Sinn tang buckle), boxes and papers. I would prefer to trade for a Sinn 156 and have other LNIB watches to even up the trade values. I can send a catalog scan to interested persons, but these are also available at the Sinn website, www.sinn.de. I am in the US and would prefer a US trade. Thanks for looking and thanks to Bob for the great site and opportunity to post!
