Instinct was to just bin these but thought they may do someone a favour. The first picture is the end of a quarter-round corner just less than 3" across each flat face. It is about 60" long, big enough to make a tidy picture frame. The colour is the same light grey you can see on the other piece.
The second picture shows the end shape of a piece of edge trim, same colour but about 75 inches long. Sorry to mix the measurements but the size of the second cross section is about 3x4cm. We are in Broadstone.
