Gold Medal Models makes an excellent set that covers the ITC/Glencoe Oregon and the Revell Olympia. An easy way to find out about it is through the Steel Navy website ( www.steelnavy.com ). Click on the Gold Medal Models icon on the Steel Navy homepage.
I haven't seen this particular set, but GMM products are extremely reliable in terms of quality. They're also noted for their excellent instruction sheets, which usually contain all sorts of valuable information on how to improve the kit parts.
Good luck.
