Brunswick Green

I would have to say that as far as Lionel (and probably Flyer) they already had plenty of plack on hand, and they were just making toys after all.

I have heard that true Brunswick green is darn near black.  Back in the day, Lionel was pretty much in the toy train business, and probably not worried about exact color matches.

When I paint Brunswick, it comes out very dark green.  I mix my own, and realize it is not accurate.

PRR used a paint designation called Dark Green Locomotive Enamel.  This was basically black paint with metallic salts added, particularly copper salts.  A freshly painted loco would look black.  In a fairly short time the salts would start to oxidize/sulphate and develop a dark green patina.  This is why no two prototype engines would look the same unless they both had just left the paint shop.  I believe that the term "Brunswick" green was used after the Penn Central merger but it was still really DGLE.

Brunswick Green is also known as "British Racing Green".

Chuck is right. Paint ages differently, depending on its original formula, weather, types of service, miles in service, and whether standing in sunlight or shade.

Photos vary, too. And when photos are published, printing inks add still more variations.

A good example is GG-1 4877. NJ Transit painted her Tuscan Red with gold stripes. She looked magnificent! But I'll bet we would have noticed differences if a time warp had put her next to a GG-1 freshly painted Tuscan Red by the Pennsy.

I like Gravely tractors, too. Colors vary from one catalog to another and even in different printings of the same catalog.

Brunswick Green or DGLE starting appearing on PRR locomotives starting with production of the M1a Mountains in 1923.  The chassis was painted black while the boiler, cab, cylinders, etc. received the DGLE paint.  It was nearly black and various experts will have different formulas.  Many models have been done incorrectly in black paint in equal amounts that have been done in too green a tone.
