Interesting stamp mark on my frame

[Dave Young]

In the process of cleaning a frame today, I came across this stamp mark inside of the right front rail. I've not seen one before. It's the only mark.

Also, my rear leaf springs have the mark of FORDX an UA on them.

Is that on your '26 or another year?
This was the only mark on my '14 frame.

Do we have a thread covering these?

There are a couple of old posts that discuss the P&B stamp.

I cleaned up the springs on my 21 Touring redo and found the name Carnegie on them in a few places. Andrew Carnegie was one of this country’s first owner of the largest steel company in manufacturing steel. Whoever was building springs for Ford bought the steel and made the springs per Fords specs. I would assume.
His name wasn’t stamped on but embossed with some type of roller that slightly raised the letters I think. It was sort of moulded in is the best that I can explain it.

I should have taken a picture of it but didn’t think about it at the time.
Now that I think about it the name was at random places. I’ll bet the springs were cut off of large steel plates to size and then arched and finished.

This is the stamp on springs I found. Not necessarily '15.

Here's the stamp on the spring. The lack of corrosion is just amazing for something finally

exposed 100 years after being clamped together!

John, the spring steel was most likely hot rolled. As it is formed, and rolled down to size, the final roller would have the name engraved into it. As the steel passes that final roller to make the finished size, the name would be left proud of the surface. Structural steel beams will usually have the manufacturers name created in the same way.
