Worldwide Stamp and Cover Exchange.  Seeking longterm trading partners.  Can trade one for one or by selection basis.  Will always send more than I receive.  Have collected 55 years.  Have naval, flight and fdc's to trade.  Also have precancels to trade for perfins.  Collect and trade revenues too.  Suggest a fair trade basis, and hopefully we can help one another.  Beginners welcome, and I can send free stamps too.  Andy Mosko, 6761 E.
