Thanks Mr. Burtle. What does that part number tell us about date and place of manufacture ? I took the shell off the tender and can't find that number in it. The only identifying number is 2671W-6, which is in that small rectangle on the lower right corner of the rear end.
When? - that was already answered above. It's from the 1974 4-4-2 Broadway limited set.
As you discovered, the shell is not marked. The information is found in the Lionel service manual (modern era). It is available online at the Lionel customer service site.
The 2671W marking is from the original use of the mold, for the 2671W tender, which came with the 671 turbine. I think it was 1948 or 1949, I'd have to check a reference book. (wrong)
I had notes on the part number because I had several NOS shells a while ago.
