Siderod, the coils are former mag wheels for model cars that I found in a bin at a liquiidator store for about a dime a piece. A little silver paint was all it took to turn them into coils. They are just slightly larger than commercially available HO coils but nicely fit in my gondolas.
Shaygetz, special orders don't upset us!
