Joe, yes I would say that is a reasonably correct color scheme. I started as a temp with the Postal Service in 1989 and I was born in 1965 so I really don't remember what they looked like in the '60s. I tried doing some research on it for you but I came up with the same picture you posted above. The few pictures I saw on the net had the red paint stopping higher than the one in that picture. The red seems to usually stop just below the flap where you put the mail in. I don't know if this was a hard and fast rule. There could have been exceptions. Sorry I couldn't be more help.

This is a picture of the arch supports that support the upper city.

Originally, I was planning on laser cutting this as you see below.

I still am but I want to add some detail to the stone archways. The stones (195) would be 3D printed and slipped  around the laser cut model where the stones are shown.

So I took the 2D arch file and imported the 2D archways into Rhino 7 my 3D surface modeler.  But the stones obtained this way would be laser resin printed with flat surfaces, very un-stone like.

Now Rhino 7 has an automated modeling feature called Grasshopper. I should use Grasshopper more 3D modeling. It's a parametric modeling method that allows changing the model design by using numerical sliders to vary the model's parameters.

So getting back to the stones. I wanted to have each stone have a random unique pattern instead of a flat face. So I found a YOU-Tube video that demonstrated how to create random surface patterns with Grasshopper.  The Grasshopper modeler for this is on the right side.

On the left, you see two patterns I created that I am testing. One subtle pattern and another with greater intensity. I merely cutout the shape of the stone's face in the pattern and move the cutout to the stone surface. Then I 3D print the stone with the pattern.

Grasshopper lets me vary the intensity with just a numerical slider. A slider varies the pattern.

when completed I will have 192 stones with unique patterns to slide onto my 2D laser cut arches.

closer view: note the randomizer plug-in on the left side that creates a random stone surface.

I'm using Grasshopper because I want a random pattern to attach to the stone faces.

Creating a regular pattern would be easier since it is just a series of equally spaced duplicates.

However, I should be using Grasshopper to do that too, so I can easily vary the duplicates.

The lastest city in a 3D representation. I started with a Plasticville  city that grew with the Woodlan Scenics and Menards buildings.

Upper City 3D

So I removed the entire wood structure supporting my earlier city; It was a series of wood addons and additions.

Used my 3D modeling program (Rhino7) I created the wood structure in 3D; This allows me to see the issues before I cut,

The interior 1x 3 girders are lowered to accommodate the 1x2 transverse beams. on the right side 2 of the interior girders are dapped to fit the arch structures shown below.

Next the 1/8" Masonite panels

Once the Masonite is fitted, I will add the laser cut streets and sidewalks. Note the grid shown in red, each laser cut  fits the grid.

Next the 3D printed stone arches and laser cut lattice truss will be attached to the edge 1x3s

Finally the edge fencing; All of these pieces have been 3D printed.

the finials on top of each fence post is not shown nor the globe lighting around the edge.

There was a highway(purple) in my last city that I will incorporate into the new upper city shown with ramping in the first image above.

the Woodland Scenics and Menards building will be added and lights connected.

I will be cutting in grooves to certain streets for the AutomotionFX wires and of course wiring streetlights and traffic signals.

finally finished the framing for the city.

the prior location was found to be way too uneven for a laser cut city. So I removed that portion of the layout and reframed the area for the city.

once I add in the 1x2s, I can next attach the Masonite sheeting.

the laser cut city sidewalks and streets will be attached on top.

SOOO  AFTER A YEAR I finally was able to get back to the Upper City. Note the Masonite has been attached to the beams above.

here are some photos of the unpainted city laser cut streets and sidewalks in place. Just the first two pieces 1

city pieces 3

the sidewalks are 1/8" (6" scale) higher than the streets. the curbs will be routed to match the curve of the sewers.

by raising the sidewalks up I have space beneath for the street light and stop light wiring.  Note holes for round sewers and square for electrical manholes. The underside of the roadways will be routed for the iron wire to guide the Automation vehicles. All of the street markings will be filled with laser cut white and yellow acrylic.

Sidewalks and streets to be painted as well.

I remember in the 50s that all mailboxes were a forest green with two different types of freestanding boxes.  The ones without the deposit flap were for the delivery man to refill his bag/cart.  There were also small boxes which where hung from utility poles.


Seems  I recall the lettering being a dark gold color until about 1960 or so.  It was white for a spell, too.

The city was just a series of computer images that I subsequently laser cut.

Until I completed the Masonite surface for the city, I did not have a way to layout the laser cuts and connect them.

Not surprisingly, after the initial layout I had to re-cut parts that did not fit.

The entire city is a grid; left to right numbered 1-10 whereas up and down was A-D.

So each section was labeled A-3 to A-10; B -2 to B-10, etc;

The cut lines were governed by the max size I can laser cut and the streets; the surrounding surfaces for the sidewalks and buildings ended at the curbs. Over the last year, as you can see in earlier posts I 3D-printed mailboxes, fire hydrants, fencing, sewer covers, tree grating, traffic signals, streetlights, and stonework, etc.;

As well as, the arch supports and other bridge works.

I discovered I have an extra 7" at the right side. Good, because I want to add several newer Menards buildings along that edge.


I needed a roadway from the upper level to the next level down about 2.5' DROP.

To do so, I needed to add a side road to my upper city. Since my entire city plan is computerized, it was easy to add the side road and laser cut the new sections.

As to the roadway,   designed and am printing a 3D roadway to do so; the width is about 4.5 " for two-way traffic.
