Frank G. posted:Lionel used basically two different shades of "green" for the fascia boards for these display layouts. Layouts from 1952 - 1954 used a bright green (similar to the Behr Park Picnic above. From 1954 until the end in 1966, they used a more muted "grey-green" like that seen on the D-190 in Jagrick's photos above. Both of these were a semi-gloss finish (the paint on the layout boards themselves was a flat finish). All were originally oil based paints. So when restoring original layouts (or making a recreation), you should know the year of the display so the correct color can be used.
Thanks, Frank. Always helpful information.
My layout (the D-105) was one of the earlier ones. 1953 I believe. So looks like I chose well with the Park Picnic green. Of course that was pure chance on my part.
