Here are two older HO gauge scenery kits.  First is a Pola #172 stone tunnel portal in a dark tan color.  The other kit is by Hoffmann, and is #611 Stone Retainer Walls.  The Pola states it is made in Western Germany (so that tells you it is older), and the Hoffmann states made in Austria.  Still factory sealed, so I took shots of the front and back, and then closeups of the wording on the header card and contents of each separately, with a yardstick in the shots for size reference.  Perhaps something for a collector, or perhaps for someone working on a layout.  Nice for layouts to get several identical so they match!  Priced reasonably, with only actual USPS Ground Advantage or Priority Mail shipping charged to the winner!
