When learning about the story about a old carbody's history either for modeling, general history or rail car preservation and the material that went into the characteristics and color value a good site is PacificNG.com
Period Paint. A excellent example of the application of material and paint or finish is Mid-Continent Railway Museum's Milwaukee Lake Shore & Western Railway
First Class Coach # 63 and chapter in
An Exersice in Paint Research. A recent NGDF message about the color of C&S cabeese and a
paint sample of the 1008 is most interesting. For the terminology of the color of paint is the
1877 Masury Paint Catalog for the following paint sample.
The wood sheathing or siding appears to Loblolly pine which is related to Yellow Pine which is good for easy machinability, medium resistance to rot and the good charecterisic to apply and "hold" paint. To see each layer of primer, paint and varish did not come out in great detail digitally by just scanning this old piece of wood in my Canon printer/ scanner but you can see the ochre.
The order of finish samples in layers starting from the oldest from are;
Bare Loblolly Pine
1) Dark Grey Primer
2) Billmeyer & Small Tuscon Red (which is lighter than D&RG Tuscon Red and more like Carmine Red)
3) Varnish
4) D&RG Tuscon Red
5) Varnish
6) D&RG Tuscon Red
7) Varnish
8) Ochre (which is like Mustard Yellow and is without a coat of Varnish)
9) D&RG Tuscon Red
10) Varnish
11) RGS Buff (which seams to be lighter than Yellow in regular Depot Buff)
12) Andy Tuscon Red (which is more Maroon and lighter than D&RG Tuscon Red)
In the above image the chips on the left that show ochre also show the sheen of D&RG Tuscon Red with the overlaying Varnish. Also of interest is layers 2-10 and 10 are very thin, layers 1, 8 and 10 is thin, layer 9 and 12 is thick.
Part 3 will be about the layers of finish and how it relates in the time line of the car.
