As Juergen suggested, I am posting a picture of some of the Sundance figures along with some other brands for comparison.
1. Preiser Welder (1:22.5)
2. Woodland Scenics Welder (1:22.5)
3. Sundance "Clem" (1:20.3)
4. Sundance "Bert" (1:20.3)
5. Sundance "Sparky" (1:20.3)
6. Industria Mechanika Deckhand (1:24)
7. Preiser Foreman (1:22.5)
8. SLM "Alex" (1:24)
9. Just Plain Folk Seated Hobo (1:22.5)
You can compare the size of the Sundance figures for yourself. One of the problems is that they don't all seem to be to the same scale -- for example the figure of Clem kneeling is almost as tall as the standing Bert and Sparky figures. I plan to see if I can use them, but they will require significant surgery to work on my layout.
