To be honest, the size of the Cats Eye is a mere guess based on the pilots seen in the original line art, as there are no known specs. (At least I couldn't find some).
Btw, right now I'm doing the SC-27, which will be posted on Shipbucket within the next days (probably the weekend). Again the size will be a guess based on the access port and people shown alongside the Star Goose on the existing line art.
Other works planned are the Mom's Kitchen, the Tunny, and maybe the Avenger II.
