Bought a tender that was sold as a 6066t, looks just like one but the number inside the shell says 1666 which i cant find in any book. What gives?

There are only a few designs for tenders. Over the years I have noticed that holes vary. Round, square etc. If you read any description, they also vary by truck design and lettering.

Tandem Train Id has an excellent site. The 2026T was listed.

Here are the pages for tenders on Tandem that T-Man was referring to:
