Hello, I am new here. Trying to identify a foundry that made castings for an antique amusement park train I am restoring. It seems at least possible the same foundry cast Model T parts. I found this discussion board when I saw the 2012 thread on the "DS" or "D5" casting mark here:
Back then, people were speculating this might have been a foundry the Dodge Bros contracted out to, as parts have surfaced with this mark on cars made well after DB were out of the picture as a supplier.
Oddly, I have a nearly identical mark on the castings for my park train, which is of unknown manufacturer. I sure would like to know what the mark means. The kicker is that my casting was likely made after 1946...but it looks so similar to that on Model T parts in the thread above. I will try posting a pic of my train part.
One other odd coincidence...some of my train castings have a part number of T 101 In the above thread, the Model T part number is T 202 Is this all just coincidence?
Thanks for any info...Rick
Might be a longshot, but a Google search of "ds square foundry" revealed that there is a restaraunt in Somerville, Massachusetts called "The Foundry" on Davis Square. Maybe the building was the old "Davis Square Foundry", hence the DS mark with a square around it?
