Try looking through this website. It has loads of stuff for Camillus. BTW, the Cub Scout knife has been done in several handle types but usually has the same blade setup. Do you have any photos?

I found this 1998 Catalog page with your BSA model and the nicer one as well with MSRP for the time frame.
