The GMM etched Ajax brake wheels are very nice, having 3D detail etched into them. However, for more correctness, you'll need to dish them before you solder (or glue) them to their shaft.
Photo (1) - Gold Medal Models etched Ajax Brake Wheel in N scale (row 10): I've been using these for years when I want a more prototypical looking brakewheel on a well-detailed model I've been working on.
But, you only get six of them per sheet, which is my only complaint since I haven't used any of the other 90 wheels...and I'm into my second sheet.

Have fun!
Cheerio!
