The internet’s a wonderful thing. I was searching for something else, of course, when I found this:

November 10 – Kadee has announced these new On30 items:
On30 Griffin 24″ Ribbed Back Wheels Sets

 

 

 

 

#300 Griffin 24″ Ribbed Back Wheels

I don’t know how new the information is (or, how old!), but it’s certainly intriguing.
