Ronald Simmons made an interesting blog post recently. I tried to go to model expo, but this is not a riverboat model site. However, I did find this link to modelexpo-online. Linked is a very nice static model kit of the CHAPERON. I have not had a lot of time to browse, but there may be others as well. Modelers, check this out:
